The first example (ie with highest p) that I don't see on your list is 15 * 25348212583^2, which appears valid from the factorizations, but I guess it is among the maxlen=5 entries you removed.
Here is the end of my log without deletions starting at p=25e9 (sorted by p):

In short, 5 in the log do not get, for the sake of search speed.
Given we're working on chains of length 11, I've now extended the code to require that the central 7 values all match.
There probably aren't any at all. It will be harder to compare/control. I prefer to output a bit more to the log and only then filter out the unnecessary.
