Thoro-Graph

I've been gambling for 25+ years, always have used DRF. and I do pretty well. I have never used Thoro-Graph, and looking at it, it looks like a chinese phonebook.

My questions are:

a.) How much do you need to bet per wager to make thoro-graph valuable

Price - 1st Product $25, 2nd - $20, 3+ $15. Individual Races - $5

b.) How hard is it to learn how to read them?


c.) anything else i need to know about the product?

thx - rob
