Key word there is highlighted in red, a holdover from the days of all LL, no PRP. Since most first testing is now PRP, perhaps a future release will adjust the assumption from 2 to ~1 for first tests, or at least PRP first tests, which would adjust the bounds selection somewhat, for greater overall efficiency of searching for new Mersenne primes.
