Offsets are only useful if the base clocks are known, but even I can admit this is nitpicking at this point... 

My most consistent results were obtained running at +125 core and +300 mem with 85% power limit on my EVGA 1080 FE; this translates into an actual core clock of around 1785 (it does bounce a bit because of power limiting) and an actual mem clock of 4811 (rock solid).

I just concluded another test of hsrminer on the Trezarcoin official pool and so far the results don't look good but I need all the blocks to confirm before I bury the hatchet on this one. Let's just say that with average difficulty over the last 24 hours (which would be conservative, because current difficulty spent most of the day below that) I should have earned 38 TZC but so far the sum of confirmed and unconfirmed is around 29.
