While I agree with the general observations about this show (and even the tier-based placement), I think you're ignoring or at least under-appreciating the 3-song start of Set II.

This, I think was a particularly adventurous and cohesive run of songs. From the 46 Days jam on, the energetic staccato theme re-emerged over and over, reminiscent of some '95 experimentation. The refusal to play the tweezer riff during the song proper - subbing it out for a drum and bass rhythm - (and especially the brief possibility of a tweezteca) seem like a good example of how the songs in Q3 were all played slightly 'off.' I would argue that experimenting with the structure of songs like this is as musically interesting as 'jams proper' and produces a continuity that is rare.
