Question is from hubs cloud documentation
https://hubs.mozilla.com/docs/hubs-cloud-aws-estimated-ccu-limits.html#estimated-ccu-table-1-app--1-stream-server

Question 1:
According to this section:

eg. Max Active CCU, single-room on t3.2xlarge = 80
Does this mean, each room will have capable to let users with "Active" status and everyone is talking, walking (which generates load to server) in room at 80 users?

Question 2:
According to this section:

Is ~1000 an average estimated user that is probably active in the system?

eg. avg. user = 500
√(500 * 2) = 31.6227766
; 31.6227766 as a Max Active CCU, single room
