Approx Quinella divs on the TAB are worked out the same way as all their divs - they add up the pool total, take out their cut (about 20% from memory for Quinellas) and then calculate the divs based on the number of units bet on each combination. Eg. If there was $1000 in the pool and $40 of that was bet on the combination 1-2 then the div would be:
$1000 * 80% = $800 (amount available)
$800/$240 = $20
So approx div for 1-2 would be $20

Sorry, I should have put more thought into how the TAB operates before making my post. Thank for your reply.
I used to have a program called "Simply Quinellas" or something by Wizbooks which Iv'e since lost, but i remember it would give you the quinella odds for each combination after you enter the prices for each of the runners. That's the formula I was after.
Nevertheless, I've found it in an old book titled "Commonsense Punting" by Roger Dedman.
Heres the formula:
1/x(y+1) + 1/y(x+1)
