Winx – what would $1 all-up on last 23 runs be worth ?

This is easy to calculate by using the E.P.I.  free data service.

Step 1 : click on WINX’s last run and then select the link to take you to ALL of WINX’s runs.
Winx-1

Step 2 : Click on the Export button and download ALL 33 runs. Save as an Excel file .
Winx-2

Step 3 : Open the Excel file and enter a couple of Excel formula to  calculate the ALL-UP return for a $1 bet using TABs and Bookies.
(to make the calc easy I firstly deleted WINX’s other 10 runs).

The result ?
Using Bookie Odds the return was $43,933 compared with TAB NSW tote which was $10,520

 

 

Boxing vs Dutching – Sandown 27th May 2017

SANDOWN  QUADDIE 27th May 2017 

MY SELECTIONS 
Today I am using the tips of  Melbourne pro Trevor Lawson who posted on the  Champion Picks  website.

Trevor’s selections were :
3, 5, 10 / 1, 2, 3, 7 / 1, 4, 5, 8 / 1, 3, 7, 11, 14
$240 for 100%

However because of scratchings Trevor’s combinations were reduced to just 192
3, 5, 10 / 1, 2, 3, 7 / 1, 4, 5, 8 / 1, 3, 11, 14
$192 for 100%

THE CALCULATION
I have selected WA TAB for bet placement. It may not be known to many punters but WA TAB (tabtouch.com.au) allow a minimum of 1 cent bets with an increment of 1 cent  … when betting online. This allows 50 x the precision of bet size calculations compared with NSW/VIC TAB with a 50 cent bet minimum. But on all TABs the minimum flexi bet % is still 1%.
The odds I have used in the calculation were the maximum bookie odds. However because my algorithm normalises the odds to 100% it’s only the relative difference in odds  between horses that makes a difference.

MY MAXIMUM DIVVY SELECTED
No maximum dividend is needed as I’m using just 192 combinations.

MY MINIMUM DIVVY SELECTED
As I’m comparing a Box Quaddie with a Dutch book Quaddie no combination will be excluded based on price.

Box Quaddie VS Dutch book Quaddie

Based on bookie win odds, the 192 combinations have an estimated dividend range between $122 and $11,656. That means if you took a Box Quaddie for $192 your payback would be somewhere within this range. But using my Quaddie calculator and betting each combination according to its estimated dividend the estimated return (no matter which combination wins will be about $815 (the estimated range is between $806 and $877).

Below is a snapshot of my Quaddie calculator worksheet and the list of the 192 bets can be found in this text file >>> Quaddie_Trevor27May

Quaddie Trevor 27May2017

Hopefully Trevor’s selections will salute and we can compare the profit from the 2 different strategies

SO WHAT HAPPENED ?
Trevor’s selections were successful with the winning combo being 10, 03, 04, 01. This combo was 7th in order of estimated dividend . My calculator estimated its dividend to  be $224 but it only paid $168 on VIC / WA TAB (even worse on NSW paying $150.50).

  • So using a box quaddie you would have outlaid $192 and got back 1 x $168 for a loss of $34 
  • But using a dutch quaddie you would have outlaid $192 and got back  3.59 x $168 = $603 for a profit of $411

WHY DO THE BETS HAVE A NEGATIVE EXPECTED RETURN ?
There is a 19% chance of getting back an average $815. There is an 81% chance of losing $192.
Doing the maths  gives an Expected Return of  19%  x $815  -> $155 which means an average loss of $37 on the outlay of $192. This is a loss of around 20% on each $1 invested and represents the TAB take out margin. This is the margin every punter has to overcome to make a profit.
Of course punters punt in the expectation that their bets will win more frequently than expected based on the market odds. And that is when profits will emerge.

 

 

 

Boxing vs Dutching – Caulfield 29th April 2017

CAULFIELD QUADDIE 29th April 2017 

MY SELECTIONS 
Today I am using the tips of  Melbourne pro Trevor Lawson who posted on the  Champion Picks  website . With wet track hitting the city of Melbourne, Trevor has gone in search of wet-trackers for Saturday’s Caulfield Quaddie.

Trevor’s selections were :
1, 8, 9 / 2, 6, 8, 10 / 1, 2, 5, 7, 9, 10 / 9, 11
$144 for 100%

However because of scratchings Trevor’s combinations were reduced to just 90.
1, 8, 9 / 2, 6, 10 / 1, 2, 5, 7,  10 / 9, 11
$90 for 100%

THE CALCULATION
I have selected WA TAB for bet placement. It may not be known to many punters but WA TAB (tabtouch.com.au) allow a minimum of 1 cent bets with an increment of 1 cent  … when betting online. This allows 50 x the precision of bet size calculations compared with NSW/VIC TAB with a 50 cent bet minimum. But on all TABs the minimum flexi bet % is still 1%.
The odds I have used in the calculation are the maximum bookie odds available at about midday Saturday.

MY MAXIMUM DIVVY SELECTED
No maximum dividend is needed as I’m using just 90 combinations.

MY MINIMUM DIVVY SELECTED
As I’m comparing a Box Quaddie with a Dutch book Quaddie no combination will be excluded based on price.

Box Quaddie VS Dutch book Quaddie

Based on bookie win odds, the 90 combinations have an estimated dividend range between $100 and $3000. That means if you took a Box Quaddie for $90 your payback would be something between this range. But using my Quaddie calculator and betting each combination according to its estimated dividend the payout, no matter which combination is successful,  will be about $460 (actually the estimated range is between $450 and $475)

Below is a snapshot of my Quaddie calculator worksheet and the list of the 90 bets can be found in this text file >>> Quaddie_Trevor29Apr

Hopefully Trevor’s selections will salute and we can compare the profit from the 2 different strategies.

Who is the best wet weather Sydney jockey ?

With the likely prospect of a wet track this Saturday in Sydney for the Golden Slipper dash I thought I would use EPI to  give me the answer.

I have now included “Track Condition” as a slicer  in my Jockey-Trainer analysis page. The steps I  used were :

  • Select Metrop in the “Grade” slicer
  • Select Randwick and Rosehill in the “Venues” slicer
  • Select Slow and Heavy  in the “Track Condition” slicer
  • Sort the resulting jockey list by the “Runs” column in descending order. This means that the jockeys with most rides are on top of list.

Now look down the list for jockeys that have a green shade in both Strike rate and A2E columns and voila !
The best mixture of Strike rate and A2E is not unsurprisingly TOMMY BERRY  !
And anyone who saw his ride on Frolic last start to beat She Will Reign would agree … it was a genius ride !

I have also matched the top 4 jockeys with their GS rides so you can see where the value bets are. It would make for a nice First4 divy :-)

Is Favourite-Longshot Bias dead ?

With the advent of Betfair and off-course Corporate Bookies offering all sorts of betting products  the pricing of horses by the time race starts  is so much more accurate than what it was 20 years ago. So does this mean that the best odds available on a horse is much closer to the real price that the horse should be ? In other words does Favourite-Longshot Bias still exist ?

Well I have just done an analysis of the last half million horse starts run in Australasia since 2014 and have published the results on the E.P.I. website.  To find out the answer to this age old question … plus be able to ask and answer your own FLB queries (e.g. do provincial races show the same level of bias as metropolitan races) then just register (its FREE) and go for it !

 

Randwick Early Quaddie 4 March 2017

With the track rated a Heavy 9 today is the day to go wide in the extra quaddie and hope for a couple of outsiders. With all the combinations I have selected (basically the filed in every race) I would have a 97% chance of collect. But I have eliminated all combos estimated to pay less than $800. So while my chance of collect is reduced to 67%  my chance of making a profit has been enhanced.

Emily Finnegan – up n coming female apprentice

It is a long way from County Meath in Ireland to Morphettville Racecourse in Adelaide but for apprentice jockey Emily Finnegan the journey has been worth it. The 21-year-old is making a name for herself, riding a series of winners in South Australian metropolitan and country race meets.
Less than two years ago, she arrived in Adelaide to try her luck after her riding career in Ireland stalled.
“In Ireland, racing is very male-dominated,” she said.
“There are not a lot of females riding at all. I can only think of three and they are not really getting many rides.

“It is more of a hobby for them than a career and I wanted a career.”

Well Emily who still claims 1.5 kg as an apprentice has been making great progress in Oz over the last 12 months. Her strike rate over last 514 rides is 16.3% (as good as Hughie Bowman) but has returned a whooping +27.1 % A2E based on TopTote3 which for all runners shows a loss of -9%.

Is Michelle Payne suffering from Post Melbourne cup Syndrome ?

Michelle had an extreme amount of hype associated with her winning the Melbourne Cup on 3 November 2015, riding Prince of Penzance, a six-year-old gelding with which she had a long-term association. Payne said she was “floating on the cloud and it’s a nice feeling”.

But how does Michelle make the punters feel who back her mounts ?

All_runs

Before I start should mention that punters who use the TopT3 product (the most popular Corporate bookmaker product where punters gets the best of NSW, VIC and QLD totalisator dividends ) will lose on the average 9% on turnover.

So when comparing the relative performance of jockeys I use the -9% benchmark.

During the period August 2014 until spring of 2015 Michelle TopT3 performance was -23% with a 11% strike rate.

MichellePayne_Aug2014_Sep2015

 

 

 

 

 

 

 

 

But then during the spring of 2015 Michelle had her 15 minutes of fame (actually a bit under 5 minutes) by winning the Melbourne cup on Prince of Penzance. Michelle was excited, the media was excited, everyone was excited that a female jockey had achieved something that no female had done before … riding a Melbourne cup winner !

MichellePayne_OctNov2015

The name Michelle Payne was etched in the minds of rank-and-file punters forever and whenever she had a subsequent race ride the focus was on Michelle rather than the horse she was riding.  Michelle was invited to the opening of everything (bar an envelope) and attracted incredible media attention. Unfortunately her race riding took a back seat and her strike rate dropped down to 7%.

But even worse for punters the loss on their bets plummeted to -40%

MichellePayne_2016_Mar2017

It’s not that Michelle is any better or worse as a jockey for winning the Melbourne Cup … it is just that Joe Public has reacted to Michelle 15 minute of fame and tends to overbet her mounts and as a result the dividends are less.

So whilst Michelle is not necessarily suffering from PMS, the pockets of some punters are !

Result of Eagle Farm Quaddie

With 2 longshots and 1 fav , coming into the last leg it didn’t matter who won the last leg (except for #17 Sister Patti which I didn’t include) as a very nice profit was to be made.
As it turned out #2 won and the divy a massive $41,553
Whilst this was the 2nd worst result , it was still very good result indeed.
