I did some research last year after one of our frustrating early losses. I found the following (numbers are not exact as I am working off memory... so give or take a few)
1. Since the last time we were ranked, a bit less than 90% of all P5 or BE programs have been in the top 25 at some point or another... could be very quick in or out. IIRC it was 10 programs (including us obviously).
2. I believe it was somewhere around 100 D1 teams that had reached the top 25 since we were in it.
Point is, there has to be some period whether our staff is doing an outstanding job or just a decent job, that the wheels should align for one year over the next 5.
And hopefully much more than that, because we should be more than an average P5+BE program.
