with the Antminer i was pulling in 0.00008000 BTC running at 1280Watts
Sorry to have to be the one to tell you this, but you got all of these things confused, you don't know what you are doing.
GTX 1080 Ti alone makes nearly as much profit as antminer S9, your GPUs were not affected by the bitcoin halving by any means, the S9 was, another mistake you did was installing NH firmware, nicehash is a shady business, mining to their pool is already risky, let alone running their firmware, you should revert to the original firmware and can still mine to nicehash.
If you are using the custom firmware you should use
stratum+tcp://sha256.eu.nicehash.com:3334
Using a custom firmware like Asic.to / Aweomse miner with Asicboost enabled you will have to use
stratum+tcp://sha256asicboost.eu.nicehash.com:3368
Mining Payment From Your Mining Wallet this was for 4 hours on my Antminer S9
0.00001692 BTC
£0.13
Based on current difficulty and estimated block fees, S9 makes 0.000124
BTC a day, or 0.00002066
BTC every 4 hours as opposed to the 0.00001692
BTC you got, but 4 hours is not long enough to make any conclusion, however, the fact that your miner runs quietly indicates that the stupid NH firmware downclocked your miner and it's not hashing at full speed.
TL: DRFlash the original firmware, use
https://whattomine.com/ to estimate your S9 profit, do NOT compare it to anything else.
