Way back before I needed glasses, I anchored right up by my eye. I can't say my alignment was all that great because, at the time, I didn't know much about what "form" was supposed to be.
After a pair of glassed become a permanent part of my face, a "high" anchor was just out of the question.
The huge gap just added a degree of inconsistency that I could never get comfortable with. I can shoot "instinctively" and do ok at close range...sometimes. That's not what I'm after either.
I want to be able to understand the mechanics, aim at something and hit it or come REAL close. There's no reason to not be able to do that at reasonable hunting distances.
Before going to a "crawl" I was going out of my way to shoot slow bows with long, heavy arrows...because my gaps were manageable.
