Location and proximity to caver populations largely affects the numbers. This is from the manual for conventions.
2 Estimated Attendance
As the convention date approaches it will be possible to make a more accurate
prediction of attendance. In general, you can expect approximately 65% -75% to pre
register at the discounted rate and 75% to 80% of the final attendance figure to preregister
by the cutoff date. This number can vary with more remote sites.
Pre registration may be higher if the convention offers significant incentives for early
registration. Because most pre registration will occur in the last two weeks before the
pre registration discount deadline, it is important to set the pre registration deadline
early enough that major decisions, such as how many guidebooks or T-shirts to print,
can be made after the deadline. Six weeks is barely enough lead time. Eight allows
more of a safety margin.
