I'm not sure prime95 is working like that. For example, if I factor M29900009 from a very low limit to a FactorOverride of 60 or less, prime95 reports a 44-bit factor 8938129290407. But if FactorOverride is 61 or more, it reports a 33 bit factor 7415202233 as well, which is the one in nofactor.

I stumbled across this because I became interested in hunting for missed factors, like in this thread. I experimented with looking for gaps in the distribution of known factors. Unfortunately large sections have many exponents where a factor is known but a smaller factor has been missed, which distorts the distribution. So I wanted to see if it was feasible to fix that first, at least up to a low bit-level.
