exactly what I did Barny

started with a base of 1000 systems.

then I applied 4 magic filters to all to get 2000

then with original 1000 I tested against each venue to get 3000

to get to 4000 I used original base of systems and removed any filters not making dollar profit.

next I tested against field sizes and race class.

my ultimate goal is to test systems with a number tools and see what combination of results will tell you what ,makes a profitable system. this is regardless of the rules or logic behind the system.

sorry about format. PC is dead and using an iPhone.
