Learning many algs a day is very easy for me. I've fully learned 4 algs (actually one and its inverses and reflection) in one class period of 40 minutes while still doing my classwork half the time. Another time, I learning 2 algs for the F perm OH in less than 10 minutes. And also the 3 new cases for Ortega 2x2 in about 5-10 minutes. (I was slow at recognition for the first 30 solves). The important thing is to know how to recognize the case fast before you learn to execute it, so that you know what are you learning. At first, muscle memory is tough for me, but now it's easy. After learning my first 10 algs, I got used to it.
But I don't like to learn more algs. I don't think it's the way to go. I have much to improve on turning speed and look ahead.
F2L:
It was a pain. I figured out all the cases intuitively. I don't think algs could have worked for me. The recognition would have been a pain.
