[QUOTE=10metreh;190422]Stupid double-submit bug - I submitted my ~350 curves at 25e4, refreshed the page and the count increased to 700. I have only actually run about 350.[/QUOTE]

only done 200 x B1=5e4 and 400 x B1=25e4!

now running 200 x B1=1e6

Yeah. The lucky curve for the c155 was:

Why were you running 55-digit curves?

Yep, aliqueit suggests about 1/4 of t45, and you've done about 2/3 of it.
