I ran this for last year on the basis that it is provincial and country meets, the fave is under $3.00, its the horses first start and its a maiden race.

Best tote
Win SR 42% POT -5.2%
P SR 70.7% POT 2.87%

and its slightly worse for under $2.

I will add, however, that it is not uncommon in those kinds of races to have two close faves and that might be distorting these numbers.
