First layers outcomes vary with no changes?  

First layers outcomes vary with no changes?

Ive been working on dialing in the mesh bed. I felt like I was chasing my tail, so I printed the 3x3 cal pattern I got from here, three time sin a row with the same settings. Prusament PLA, feeding out of  a heated dry box. I have a hot end sock (its clean and not dragging or anything). Especially the middle and right side seem to vary quite a bit print to print. I have a linear rial upgrade on here and the bed is very solid. The bed is very clean, and I hit it with IA after laying it down. At first I thought the bubbling in the middle might have been filament issues but its dry and the next print is fine with the problems changing to the right. Any ideas? Pics in order first to last, no settings changed, temp cal was run right before doing these three. The third is especially bad, but again...no changes.
