Other than the obvious pain of the delayed awards (which wouldn't have been nearly as bad if they didn't pile us all in that sweltering gym immediately beforehand), it generally went pretty smoothly, at least from my perspective. (Then again, I've seen much worse, like Cornell 2019...)
In terms of events, here's how I'd comment.
Detector Building (1st): Event ran well, with few issues (bar me forgetting a second thermometer to calibrate against -- luckily we had one floating around in a Chem Lab box, which turned out to be far more accurate than the last one I was using. A terrible fate turned into a nice surprise with that one.) The event supervisors were friendly. My only "gripe" was that the range of temperatures that were sampled was fairly narrow, and all of them were in the "blue" section. My green and red LEDs sat dejected and unused and I had to console them afterwards.
Circuit Lab (2nd): Yikes. The lab itself was very easy and didn't pose much of a challenge. The test is best described as "vector hell." The latter half, mostly electronics and capacitor-heavy, was very fair, and we did rather well on it. The first half was a mess of electric fields and fluxes, made worse by the oddly-shaped math. Pretty sure this would either require a massive formula sheets or some integration. Unfortunately, linear algebra isn't one of my strong suites, so I basically used multiple guess techniques for the whole first half.
Sounds of Music (3rd): This was the last event of the day and generally fairly cheerful. The test ran well for us, except for a handful of questions. We didn't have phon/sone stuff in the binder, and trying to identify the intervals in the Star Spangled Banner was very, very difficult. They were probably thirds or something but I'm not sure.
Code Busters: The test was unusual. A lot of teams got the bonus very quickly, obviously recognizing the quote. We took quite a bit longer but still got some bonus points. For the first time in (many) tests we got the Xenocrypt as well. Notably, some questions/ciphers that were usually assigned high point values (Morbit/Pollux, etc.) were assigned lower ones, something that might have affected our placement. I ended up skipping a morse cipher when I saw there were three "space" characters in a row (or something similar, I don't remember.) I haven't gotten a chance to look at the test yet, so we'll see what that actually was.
Chemistry Lab: (35th, oof): Not sure what went wrong. This could simply have been due to similar scores and a great number of teams present, but I think there was something unusual about the event. Perhaps the supervisors didn't like us using all three NaOH pellets (I'd like to say it was planned for better accuracy, but it was just because I added too much HCl, since I couldn't stir/add at the same time). I'd like to hear what anyone else thought of the event. Cleanup was a little more difficult for us because we had no working taps at our table (and had to use beakered water).
