I don't know what your level of experience is, but in my 40 plus professional years I've found:As a rule, I do not like 'creeping errors'. Wall isnt plumb, floor isnt level, corners arent square, siding isnt straight... not my problem. If you have to fudge it, then do so, but Id be damned if I set my switchgear out of plumb b/c the carpenters hosed up. My OCD would require a second level to verify my gear was plumb, but if it were, well, forget the framing. What if they decide to repair it at a later date, but cant , because your gear is flush with their messed up wall?
At the end of the day, week, month, year, life (perhaps), it's how it looks, not how it measures... for most things. :happyyes:
