I'm saying ...it is essential to stand there , with a
sling psychrometer ( and a superheat slide ) , and watch the temperatures fall...while running to watch your gauges. Do this for a year or so on multiple systems...and explain what you feel...on the suction pipe , in the structure , outside. Im just saying that it gives one a sense of " feel "...no " contradiction " of your math at all ( or anything you stated ) . You posted the truth ( I think )...I said that it was hard to read ( as compared to the slide chart ). We are on the same page.
