N factor change 13 minutes.
Quote from bumface on page 579.
expect an N factor delay withing some time (extending the gpu era)
That's for the next N-factor. Not for today's one. (5 minutes now)
I'll come back and play for a little bit with the ultracoin miner and see what I get when it changes.
edit: are you sure it hasn't already changed. I got all HW errors as soon as I started with my old miner settings that worked last week. ]
edit: and my rate is halved.
