Well, no it's not really. Speedway has a points limit, otherwise, what you are suggesting, the teams with money would be 1-7's of 7,8 and 9 point riders, while all the others would be 2, 3, 4's etc.
And, as I keep saying, just because a rider "demands" a certain amount, clubs don't have to pay it and at the end of the day either the rider reduces his demands or doesn't get a ride.
