If they split the points in the crossovers, they create a larger gap between BM100 finisher
Actually it would create a smaller gap. If you're the top finishing BM100 boat you'd get 200 points regardless of where you finish in the overall field. If you're the second BM100 boat you'd get 199 points. As it is now there is a huge gap between first, second etc.... in a given horsepower division.
