I think you have a mix of backgrounds coming in this year. If a judge is actively teaching I think they're a bit more understanding on this year. Retired judges may not honestly understand the ins and outs of having a tuba player, a 1st chair clarinet player, a 1st part trumpet player, and another player being out for COVID the week of your contest. It's been impossible to guess or control... and I guess we all should have played baby simple music and not pushed anything if you go by that thought process.
Personally this year is beyond crazy. My personal thought is to give much more grace than I normally would. I definitely gave a couple of ones out that I would have made a two on a normal year. I followed the rubric and focused on the things they were doing well though to still justify it.
My opinion is that anyone giving a 4 or a 5 out this year is completely out of touch with reality. A 3 is a new 5 in my mind this year. If I can justify a band having success though this year, maybe that's the one thing that inspires that kid to feel proud of what they've done and stick with music. This is not the year to be judgmental in my opinion, but rather the year to help lift up all of these struggling programs.
Bottom line, I don't know what kids that group is missing. If a part is missing, but the rest is being played well, I'm not judging against that missing part at all this year.
