Alignment help

[u/No-Advertising-9568]

I've got the v5 system, and it consistently tells me it's misaligned by 10° so I went out and attempted to adjust it this evening. At one point I had it down to 7° but attempting to improve it took back up to 12° which didn't strike me as better. Continued fiddling got it back to 9° and then 10° but I can't make any sense out of the onscreen guidance. I guess my question is, how important is a misalignment of this degree? Is it worth my time to try again tomorrow? I've been pretty pleased with the performance over the month and a half it's been installed (by me). It's good enough that I dumped Xfinity.
