The current method has a reasonable ratio and works just fine .The current method allows kids who co-op to spend more hours at work because what happens is there scholl day is shortened by two hours which means they get two more hours of making money to pay for their gas ,insurance,vechicle maintence,or what ever other expenses teens have.I mean your method would really put the screws to co-op kids somethings are best left alone I think this is probably one I hope this fizzles and bombs.
