It already had one factor, now it has four more.
67.472 - 66.121 = 1.351

By that measure, then, these four are bunched up even closer:

67.221 - 65.933 = 1.288

I had been running GPUto72 for a couple of weeks. 23 digits each. I did not bother with bits.

If you want to look at it this way, yes. GPUto72 is currently running to 76 bits, a prep for the next step. Before, this would be P-1, but now, I am not sure.

I too have found a 39-digit factor. This was on 5/05/2019. Mine was ECM. M83621. It is here. I never checked on any list to see if it was there. Doing so never seemed important at the time.
