Are capacity estimates useful?

[tidoust]

I am wondering whether it ever makes sense to display the group's estimated capacity (e.g., 20-29) in the generated table. I say this because we don't actually generate the schedule until we have registration data, and once we have registration data, we should use that (and warn when the real number of registrants exceeds the room capacity).

I moved that to a new issue because I am wondering whether we actually need to ask group chairs to estimate the number of participants at all if that's how we proceed.

I'm fine not displaying the information if it isn't useful. I would prefer that we stop collecting it altogether. We're not collecting that information this year for TPAC breakouts. I don't know if that was intended (or the result of a copy-and-paste from the breakouts day form), but that seems a good thing to me: I don't know how to estimate the number of participants for breakouts I propose.

If an estimate is still needed for group meetings, we could also compute one automatically: multiply the number of group participants by some magic ratio, et voilà! The magic ratio could be adjusted per group based on attendance numbers from past years (which could also be automatic). We could at least give it a try and see what we manage to come up with.

If we need manual adjustments per group, that would essentially mean that we need to be able to continue collecting the estimated capacity. That's fine, we do it already...
