The meeting itself

Capacity is published per plan (100/300/500 per room, >500 as a bookable add-on) with 50 breakout rooms per room and simultaneous screen sharing — that clears rubric level 5 on scale and features. But nowhere does the evidence evidence moderation controls, a waiting room, adaptive bitrate, or what happens on a bad connection, which caps it well below 8.

The hard numbers a buyer can hold onto are 300 participants and a 30-hour meeting duration, published per plan, plus apps for computer, tablet and phone, meeting apps and room hardware. Beyond that I found no public information on screen sharing, breakout rooms, host moderation, waiting rooms, or behaviour on constrained connections — the mechanics that decide whether a call survives a bad network.
