Guys I want to ask You about mining efficiency.

I'm using z-enemy miner 1.28 and mine with GTX 1070 + 200 core + 0 mem latest drivers Version   417.35 - WHQL,Release Date Wed Dec 12, 2018

Power consumption by each card is about 145W with efficiency 0.99 to 0,16 MH/W depending on current algo (on Power target +0)

I have switched power target to -30% and now power consumption is 102W/1GPU and efficiency is from 0.086 to 0.18 and I have seen even 0.24MH/W

The problem is that i can see significant drop in mined coins and my question is what settings do You use and/or recommend if I want to mine as many RVN as I can with energy wise settings?
