For those interested, I have a handful of antminers pointed to NH.   Here are my daily payouts in BTC (not fiat!)


1/30 .00619026
1/29 .00603829
1/28 .00519994 (had them off for a few hours)
1/27 .00627538
1/26 .00582347
1/25 .00673093
1/24 .00718845
1/23 .00726570
1/22 .00717737


So in a week's time, the profitability has dropped ABOUT .001 BTC a day.    Based on all the hype and extra people starting to mine and the drop in BTC price in that same time period, I'd say thats not an unreasonable change.   Not happy about it, but we couldn't expect an L3 to continue to make $30 a day forever.
