Answer

Hi...I doubt if anyone can clearly name the gradations. I have confidence in Campagnolo...it fits for fast riding (9) and steep passages (42). Forget the influence of the chainring...that makes the music.

I have all three EKAR cassettes and the RACE is my favourite...but I also do 13,000 km a year. Quality is top. Change to a wax chain and stick to Canpagnolo's specifications for the chain and you'll be well served.
