Typing technique for different texts.

Hello!

Probably my first post here, but I noticed that faster typists, typists who average around 150 with any random 10 tests, have different typing techniques for texts of different length (think endurance and burst techniques), whereas I almost always mess up on shorter texts of lengths around 1-2 sentences. Could this have been caused by using exclusively one technique for all kind of texts? Or am I making things up?

Like several other people on this sub, I plateaued for nearly a year now. Now, I don't expect my WPM to increase monthly or bi-annually, but I'm looking into solutions regarding the more subtle sides of this craft, i.e., the mental state during a test, the rest periods between every n tests, or even optimizing typing techniques for different texts. Especially rest periods, because I want to think of typing as a workout and there must be a short rest between sets, and I'm not sure how to go about it.
