Thank you Ithaca, thank you for your response, very interesting!
However, a missunderstanding
Ithaca I used to feel the same as you; I didn't see the point in "resting", as opposed to napping.
I do see the point in resting! Very much so! But I don't see the point in ten minutes resting before practising. For me, anyway. I am early retired, and practising is always the first thing I do in the morning, and the moment I need to rest the least.
But, if I would have worked all day, I would certainly need to rest before practising. Actually, when I did work all day, I was usually way too tired to practise, resting before practice or not.
Ithaca So not only is there no one-schedule-fits-all, I've found that there's no one-schedule-fits-me-always.
Very true! You are quite right. Plus, no one-schedule-fits-the piece-always. Some pieces demand a lot of work in the beginning, for instance, pieces with an unusual rhythm combination in three voices, but once you get it, there is no need for many repetitions. Whereas other pieces (my Bach) have just two voices and an easy rhythm, but all measures are different and they need a lot of repetitions.
