Really only a few hundred potential words? My back-of-a-very-small-envelope guesstimate was about 2000.
I’ll be interested to see how many there are, because my envelope isn’t big enough to work it out, and the walking algorithm which I am really impressed can be so fast.

But anyway checking even a few hundred potential words (the vast majority of which would be non-words so the worst case) is going to be slower than checking a much smaller number of mostly valid user candidates. Both can one done in idle time so not a problem I guess.
