Less is generally more with this technique. If you don't rob a local area of solar panels and can more evenly distribute light by removing a leaf, go for it.
if you always have a reason/system for doing it, you can be confident you don't do too much. That being said, stuff on outer rim of plant looks fine. if anything, the inner portion... alternate what you take off at top or 2nd level to spread it out evenly, bend what you can elsewhere... maintain full coverage.. don't lose light to the floor.
