How did you make this estimate ?  Fit an exponential curve to the known
primes, and extrapolate the 1st one that should have at least 1m digits ?

I think I used to know how to do that, unfortunately at this point I have
little idea.

Why isn't something like this used in GIMPS to select numbers to work on ?
-- use current known primes to estimate the location of the next, start
allocating numbers to work on at that number, and keep alternating +/-1
till it's found.... ?
