To the OP, it's not that big a deal. Most racers don't keep their batteries until their last usable cycle, nor do they keep count of how many cycles they've charged anyway. If your race program moves so fast that shorter charging time is really important to you then it's fine to charge @ 2c. Even if it cost you 10% of your cycle life, you'd never miss it.
Regardless of what my charger says, or what studies say, the best "proof" is what I see at the track regarding my own packs.
I agree with what you say about most racers not keeping their packs until their last usable cycle and never missing the last 10% of their cycle life. That is the other reason why I don't worry about charging at only 1c rates. To me, it's pointless to spend more time charging.
