Strange, large dots with Kodak Plus-X and Kodak XTOL 1+1

See my earlier post on presoak. Kodak has recommended it since the 40s to promote more even development.

I'm thinking condensation due to the film being stored below freezing and brought into a high humidity and warm atmosphere prior to exposure.
I can't be sure of this but dampness may change photographic sensitivity slightly, that may account for the difference in density on the neg.
Just a guess...

I'm just wondering if I presoak how much the development time is adjusted. Can't find any sensible information on the net - adding 50% to development time (like the source I quoted suggests) seems a bit long to me.

I do not adjust.
