Later edit: total hashrate from nicehash is now 2.6 TH.
Diff 13k (not 9K at least like last time). Hashrate from NH went to 1.5 TH for X16r (not all goes to Ravencoin but clearly most of it will).
Let's see how it goes now?
One thing is clear however. All that nonsense of FPGAs was just that...nonsense. Real culprit here is NH.
Like mining on FPGAs or on GPUs makes any difference, if the users of either FPGAs or GPUs point their machines to NiceHash, only bad things happen. At least FPGA users are less likely to be script-kids who will throw their hash to NH. Also it's not possible for FPGAs to mine on multi-pools, those pools automaticaly point miners to Raven when the profit high (=diff is low) and then leave when the profit gets lower (=diff is high).
This is not going anywhere btw... we hit 2.7 TH hashrate, in a few hours the 2016 blocks will have been mined and the diff will shoot up to about 60.000 I'd guess, and since the profitability will nosedive, all the miners will leave.
With sadness I had to sell 75% of my RVN since I'm afraid of what will happen when there will be no miners to support the network, and I've been gathering them for months.
Maybe when there will be FPGAs miners supporting the network, the NiceHash's hashrate won't be enough to create problems.
