OK...
I think I know the answer to this... but want to double-check to be sure... While doing factoring... using ECM... factors up to: 15 digits is the equivalent of ~2^50... 20 digits is the equivalent of ~2^67... 25 digits is the equivalent of ~2^83... 30 digits is the equivalent of ~2^100... If trial-factoring has been done up to 2^68... is it possible to skip testing ECM curves for factors up to 15 and/or 20 digits... and go straight to testing ECM curves for digits up to 25 digits???
