Well if it's a greyhound system you've got a choice of numbers 1 to 10 at the end of the month. Lets say the top 6 trap numbers at the end of a month of collecting results are 1, 3, 5, 6, 9, 10

So you use these numbers to box trifecta 20 sets of 3 numbers?

Which particular race do you bet on when the anniversary of a month is up?
