Thank you, BA, but my asking for "considerations" was more like "compensations", as my personal playing style/technique is not a traditional one. I only sometimes stand far back from a shot to 'see' it, as I more see/imagine the shot line, get my cue on it, and the get down to shoot--often, I put the cue on the line and then settle my body around it. My point is, when I see someone standing more upright, I think it introduces a..."parallax" is not the word, but I *feel* that the shot sighting is compromised by the greater viewing angle (between the cue line and the downward sighting line). I now understand that achieving the right alignment somewhat negates the height/angle issue.
My motivation for this thread came about from when I have wanted to help a lesser experience player, one that has a high stance, I found that I didn't know how to address that--because I don't employ the standing-aim method, or at least not giving it enough time to realize that the elevation doesn't matter, if that step is employed to ensure that the elevation doesn't matter!
I apologize for any lack of clarity in this--really, any of my posts. I often have problems with overcommunicating, because I want to include nuances, but typing out every thought-counterthought gets messy....
