As for how i stake them i just put the same amount on each selection....that way when the big ones come in you are not disadvantaged by the dutch system...as long as it pays $3 or more you are in profit.....as for the class i don't have a class list in front of me but for city races it starts with restricted events (1 metropolitan win or 2 metro wins or maybe restricted to fillies or 2yo or 3yo)then im think it is class 6 races then comes welters then open races then quality then you have your group races i will only put my money on top grade races like welters,opens,quality,group races.....i never bet on 3yo races unless they are quality or up same with 2yo i never bet on fillies/mares only races.....by doing this i limit the amount of money i have at risk.....i think on average there are about 50 to 80 races on a given saturday....no one i don't care how good you are can make a profit trying to take them all on.....i have between 5 and 15 bets on saturday and about 1 to 5 on wednesday.....plenty of action....i use a bank percentage bet for example i bet 5% for 1 to 5 bets 10% for 6 to 10 bets and 15% for 11 and above bets.......i just devide this amout by the total number of selections for the day....on wednesday i had 12 selections for 3 wins for about a 500% profit.
