I have a different show rating system that I prefer to yours - sorry but more accurately, not sorry. I've never seen/heard/been made aware of a (non rain affected, normal) Phish show in 3.0 or 4.0 that deserved 1 star and only a few 2 star shows under my system.

Wisdom of the crowd is generally pretty good at identifying most popular shows within a tour. Cross tours/years/eras becomes tricky but basically anything 4.4+ is a stupendous show regardless.
