I would think that if you are improving your shooting by doing something different, then so be it.
I am a better shooter than I was years ago because I have tried different things in the hopes of improving. Some things I have kept in my routine, some I haven`t.
I tried what you described for a while, and eventually just omitted looking at the arrow point. When I draw my bow, I do not pay any attention the the arrow at all. My pea brain has all it can do to just focus on the target. :D
