position percentage would be a possibility, but I always find I can get much better scores at summer show/fete/carnival runs which tend to have a "softer" field
comparing against the winner's time is roughly equally challenging at every race - plus it encourages you to keep running hard even when your position is pretty much settled
as regards number of counters, a champs should be (partly) about consistency throughout the year, but maybe we should drop to 6 counting "month-best" races
I'll start another thread soon, unless we want to get Brett to change the title of this thread...?
