Al,
Attendance X 5 is still an erroneous assumption of demand. Do you really think there are only 120 AC LE collectors?
I did not put words in your mouth. You did equate demand to attendance. The number of chips each person can buy at a release is not an issue when evaluating total demand. The number of collectors that want the chip is the demand. Most of those collectors can not be at a release (or choose not to attend)and depend on others to get chips for them. This includes NIS, friends, dealers, Ebay sellers, trade partners, etc.
Pete Sanders has already replied to your comment about a Hard Rock release 5 chip limit so there is no need to comment further on that issue.
