As you can see, some years you lose more than 20%, some years you lose as little as 4.59%

Under 10% it would be quite possible to make a small percentage using best tote.

I'd recommend using Betfair and setting a price limit on your bets, if it's matched go ahead, if not, pass the race.

Sticking to hot favourites under $2.00 you only lose 7.83%, but you are far more likely to get "value" on the easy favourites. For example you won't get $3.00 about an even money shot, but you might just get $7.50 about a 5/1 shot.
