No go the other way. The logic throughout the entire system is a 1 in # chance. So in all cases where it's a MaxChance property, the higher it is, the less likely it is.
MaxChanceThose=1 is a 1 in 1 (100%) chance
MaxChanceThis=5 is a 1 in 5 chance.
MaxChanceThat=1000 is a 1 in 1000 chance etc
And btw not even sure what would happen when it encounters a 0 since it is using a randomizer object. But anyway don't go less than 1 on anything.
