Awesome, will test asap !
on my 1080Ti rigs,
Nist5
Palgin Ccminer 1.1 x64 > 395MH
Excavator 1.3.9 > 385MH
Neoscrypt
Palgin hsrminer neoscrypt > 7600MH
Excavator 1.3.9 > 7050MH
So nearly here, but not yet

Still to be thorough i will observe for one hour the average hashrate reported on pool on both algo. I tried to tweak a bit with the parameters for both algo, but it result in lower hashrates, seems like you optimised them pretty well already as parameters goes.
We'll put some more work into Neoscrypt and Nist5. Let me know how the pool speed comparison results out.
