Dear all - I am in the middle of trying to work out projected returns on trifecta bets.

If a div is published at $10,000 it is fair to say that if you were theoretically an extra winner then you will get approx $10,000 for a unit.

I want to work out what happens if you theoretically had 10 units on that particular trifecta. Obviously the final div is then reduced due to pool limit and the fact that 10 extra units were winners.

I understand the mathematics and have made my own projections but how do I find out how many winners there were when a particular dividend is published??

I have seen trifecta divs published at $10,000 when the pool size on an internet site says the trifecta pool was $7,500 only!!

How can this be and how do I get the right figures? It is very important that I learn this lesson as it directly affects a project I am working on at present.

Anyone that can help please do - I would be forever grateful.
