Hi All,
Does anyone know the formula the NSW TAB uses for calculating Quinellas.
Any help would be appreciated.

The 'formula' for the Quinella is identical to that used for win, place, exacta etc etc saving the deduction differentials.

The gross pool less 15% (or is it now even more - 20% WA TAB) divided by total number winning units = final dividend.

The deduction component has been described by some as "corporate greed". Others say the rising cost of a bet lies squarely at the feet of the lazy, apathetic and ignorant punting public.

Thanks Dr Pangloss,
I wish to use a formula in my spreadsheet where I am attempting to set up a plan to bet Quinellas. I intend to dutch some runners. I have set up a sheet already to do Trifectas and this required a complex formula consisting of the multiplication and division of Horses 1, 2 and 3. I assume there is also a formula to work out the Quinellas comprising the use of the prices of runner 1 and runner 2, as is the case with Trifectas. This is what I'm looking for.
I was hoping some forum members have already set up such a sheet so that when I update the start prices, I can work out an approximate Quinella return for the runners I select. I can't see how I can get this information from the method you suggest. Do you have any other thoughts that might assist me.

Thanks for your reply.
Kind regards,
Ralf

Get in touch with Malcolm Knowles and see if you can still get a copy of his brilliant book called Quinellas,and the software called Simply Quinellas.Neither are expensive,the software used to be 29.95,when I bought the book it was only about $5.Don't know if their would be any left as I got mine years ago.Not sure of his web address,try http://www.inracing.com.au
Can't give you any formulas because copyright laws.
Hope this helps.
cheers

A simple question needs a simple answer what they want if i am correct is the estimated payout of the quinella....this is the easiest way i know of and is pretty accurate
multiple the first horses win price x the second horses win price then devide by 2

as an example i went to a randome race
saturday sandown race 4
results
6 SARAH MICHELLE 7.00 unitab
1 DON'T TELL EM 4.20

7.00x4.20=29.40/2=14.70
the quinella paid 17.50

i know this is a little higher than what was estimated but unless you have all quinella prices of payouts in front of you this is the only way i know
this will work for exactas but the difference is you don't devide the result by 2 unless you have included the fav to win they always pay less.
One last interesting fact if you do this calculation for all the runners to find out what each pair will pay if comes out to about 118% market....like the win portion...i thought that was interesting

Thanks Shaun and PurpleHeart68 for your help.
Kind regards,
Ralf

Agree with Shaun's quick estimate formula - it's surprisingly accurate.
The only commentI would add from the testing I did was that quinellas in small fields (7 or less runners) normally pay less than Shaun's calc. My suggestion in small fields is to multiply the calculated dividend by 70% to get a closer estimate.

Amralfff1 asked, "What formula does the NSW TAB use to calculate Quinellas?"

Be careful what you ask for Amralfff1 - you might just get it.

Have a look at the discussion found under 'free exotic help' at the Forum sponsored http://www.capitalinfo.com.au which may save you from repeating Don Scotts' exotic bloopers.

NSW TAB Quinella dividend approximates are available on a grid display up until the jump.

Thanks for the direction Dr Pangloss.

Ralf
