No exercises. Just follow the course. If it’s not in there, no need to be doing it. Note that I can’t really provide support for scenarios where we’re not following the course.
You’re on the right track with measurements. I see you joined recently, note that it takes weeks at minimum, and several months for full adjustment to any change in habits or diopters. Also sometimes eye chart improves, other times centimeter, other times distant land marks.
This is a SLOW process.
