Where the Wagerd Dollar Comes From And Other Questions

[SentToStud]

Let's see how this comes up...

Assume a Thursday at Churchill. What percentage of total wagering is done by:
1. Owners/trainers/others working in the sport?
2. Big (say 300% of ave per capita) bettors not working in the sport?
3. Everyone else?

Assume on-track and off-track betting patterns are identical.

I'd say:
1. 5%
2. 90%
3. 5%
