Maybe he uses GMPECM and doesn't want to email results without factors? And uses a lot of computing power to compete 5560 digits range for one exponent in few days.
I believe the problem with curves and bounds is the problem of version 29.6 which I am using. Perhaps it submits results in JSON format which is not parsed correctly by server. Text results in results.txt look identical to previous versions. By the way I found another 40+ digits factor with 30 digits bounds. I am curious what is probability of such discovery? [Sun Apr 14 07:19:46 2019] ECM found a factor in curve #147, stage #2 Sigma=7835381084152872, B1=250000, B2=25000000. M389749 has a factor: 35157083141838820140048845608443589051481 (ECM curve 147, B1=250000, B2=25000000) 134.69 bits

That makes sense. It was probably the case. It is just a pity the whole amount of curves done wasn"t reported.

Indeed. The default value (2500) for the ecm progress table will soon have to be raised or the table will display no values at all...

M2377 just had a factor found
This was the 6th smallest M without a factor!

Where and how can you check bitlevel on a factor?
