Hey kozmos,
as I already stated in my previous post, the production rate of the next higher chain level is reduced by factor 10-15 - based on personal observations. I'd expect you to have an average output rate of ~3 Shares/h => 72 shares/day => ~0,6 XPM per day atm, when running your miner continously.
Tips on tweaking I can't provide, to be honest I wasn't able to establish a general pattern for setting up mining machines til now. Usually the default setup using primoral 61 and Sievesize 1M-1,5M always worked best for me.
