Okay, I'm basing my calculations from Cooney's Megastore story:

The session started 1800h to 2115h (3.15 hrs). It took him approx. 30 sec to complete his signing. So, at least 378 people got autographs. However, Snatcher did mention that he recalls about a couple thousand people present and believes Alizée could have done no more than 500 signatures.
MixUp session to start at 1800h but no end time given:
500 braclets * 30 sec = 15000 sec >> 4.17 hrs
Interestingly, I read, in the Mexican forum, their understanding is that on the day of the signing you first need to buy a CD and then register the ticket (I guess sales ticket?) into a raffle in order to obtain a signing braclet. So, no first come first serve?
