I'm not certain what you are getting at.
In my case, there are certain climbs and other segments that I will get a new personal best on after being off the bike for a week or two. But since I like to ride more than I care to get a personal best, I'll just keep riding as often as I want.
Likewise, of course frequency, sleep, stresses from travel and need to perform affect both professionals cyclists and all cyclists. If we were to have enough rest and time to de-stress between each ride, our performance overall will suffer more. I think it unlikely my body would have built itself up to the level capable of making that PR if prior to that week or two off the bike I hadn't rode 14 of the previous 17 days.
So what's the point?
