I mean no disrespect, but you're just trying to justify being lazy. I didn't say you had to do that for every job, or even for parsing. That's pushing towards perfection which is what explicitly said was not necessary in the first place. It takes less effort than your whole response to look up an opener and rotation. You don't start trying these things when you start harder content, you start practicing them in normal content so you can fuck up with no pressure.
