All of these are excellent comments! In particular, I had not thought of the lack of audience tapes--I get to listen to every show via LivePhish+ and forgot that not everybody can do that.

Venue size is also an interesting angle, and one that I absolutely should have considered. That should be easy enough to test.

As for "expensive destination events", the obvious comparison would be the Sphere event in April 2024. My data go only through October 2023, so I can't look at that. That said, four or five nights in NYC (or Miami) for NYE is also an expensive destination event. The complicating problem there is that NYE has so much history and lore that the comparison does not seem equal.
