This is consistent with my experience. I agree these norms are good and make organizer’s lives easier, but there is always a drop out rate and it is possible to plan for that. Did Berkeley have an unusually high number of noshows? For EAGxPrague we worked with an estimate of about 10% which ended up being quite accurate. I don’t remember the exact number but I think we had about 450 registered and about 410 showed up (this does not include the people who actually canceled since they no longer show up as registered in the system). I think it would be possible to do a more detailed analysis of the drop out rate in time and the final number of noshows in case it’s useful for future organizers.
