It is not unexpected. You just have to consider the top 100 or so are either near retirement or have been here so long it is not worth starting over. As the number goes down the list the greater the percentages of people taking the SSP will go drastically go up.
Yep. I'll bet most of those guys are close to if not over 50. Chances of Endeavor being around for 10 more years is good so they probably just don't want to start over again. I know alot of old ExpressJet guys who had guaranteed interviews at CAL that never took a chance because they were in the top 100. There were even a bunch of those guys who had flow rights without interviews that stayed at XJT.
