Estimated T-Level: 48.5 ⓘ

TF below 2^156 is very unlikely to find new factors due to ECM effort.

45 near-duplicate ECM records are not shown in History (below).
Near-duplicate in this case is when something like "1 curve completed" is reported multiple times by the same user on the same day.
Please try to do 10s or 100s of curves at once instead of reporting them one-by-one.
