In my opinion the gap in level is huge between say 700 to 750 to 800, the value of the rating itself is like exponential. Nobody is 800 "randomly" but many are in the 700 just by participating a lot and not having too much stupid races. Takes a bit of time for your rating to settle, about 100 races at least.
The real meaningful stat is the win/top3 ratio, you can tell who s really good in a split regardless of the rating. It might be a bit easier to get wins regularly in daily's than other types of events but still the better indicator.
