The problem with 30 seconds, 10 mins etc only, is it penalises those racers who try their hardest to hang on for as long as possible then get spat out the back, to be picked up and most likely dropped by any chasers. It incentivises tempo riding.
I though it was results based? The old cats were pretty good apart from the sandbaggers who hung on for the final sprint - but they would be promoted if the new setup was purely results based so they would be found out quite quickly and placed into the correct pen. Hopefully it evens itself out soon.
My real ZRS is probably closer to 350 (maybe lower) at the moment and I'm sure a few more races and i'll be down there and I'll see others in the race longer
