Any insight into times in the morning?

Next week, I'll know be leaving on a UA flight at 10:30 (Tuesday, which should, I presume, be a little quieter than Monday). I think, at least pre-COVID, the most busy times were flights in the morning up until about 9 - 9:30, This is a little past that, so hopefully I'll miss the bulk of the crowd, but maybe there will still be some on the tail end? I have GE, so that customs portion, at least, should be quicker. Though I'm kind of wondering if it being post-labor day, and biz. travel not back for the most part, if it will be quieter again.

Is arriving around 8:30 (T - 2 hours) too early? On the risk spectrum of arriving too early or too late, I'm usually on the side of arriving earlier,. But with the situation in general, the TB lounges all seemingly closed, and limited services once all cleared, I'm thinking I'd rather spend less time in the terminal. Thoughts?
