After a quick calculation, I realized it should have taken about 1h and few minutes to complete the 4 character space at 4*940 p/s, but it's no big deal. I'm just very surprised the ETA can be so wrong on a short session. May be it's too short to get the opportunity to adjust, as I've seen in previous multi-day sessions.

I'm pretty sure we have a bug in mask mode ETA calculation but I've yet 
to nail it. There are so many combinations: node/fork, resume, hybrid, 
GPU-side mask and so on. In most cases, ETA is correct but sometimes I 
notice it gets screwed up.

In this case, you used fork and pure mask. Maybe we should have a closer 
look at that. There were incorrect bug fixes in the past, that fixed 
something but broke something else. Those fixes were reverted but the 
original problem may still be present.
