What do you mean by “not picking up”? As in registering after being accepted? It is certainly the case that some people think the way you do. Also, many people procrastinate on finalizing their registration. Now, how much of which is in your “unclaimed tickets” pool is an open question. For EAGxPrague quite close to the application/registration deadline we had maybe up to 150 people who were accepted but haven’t registered (and I had roughly 500 capacity). Not knowing if they are not coming or may just all register on the last day made it harder to accept other people and plan meals etc.
Once there is a confirmed registration number, that’s a bit easier to work with regarding estimates of who will show up but I find the conversion rate of accepted → registered more unpredictable. Especially since it was possible to apply for more conferences at once.
