I understand past payouts are not meaning future will be the same jim, that is down to variance. However they are normally in a similar ballpark, for one to go from 0.01 ish on EU day 1, to 0.005ish day 2 on US, to 0.01ish on EU day 3, to 0.005ish on US day 4, you can see there is a trend occuring to a decent reliability. I am not taking sides, I am merely stating you cannot dismiss it.
I'm a massive fan of the pool, don't take everything as an attack of so personally, a loss of 50% earnings day to day from going EU to USA server is very strange, and not within the realms of variance - as you will be able to see if you look up others payouts.
