hi all,

total noob here, been mining on wafflepool for the past two weeks, with decent results but have some questions regarding the stalerate, since i am new to this i have not found a guide that explains all the different things in cgminer i.e. thread concurrency and intensity and all that.  I copied my build from a youtube video i am running 6 r9 270x's with a h81btc motherboard etc...  i have been successfully mining for the past two weeks using an intensity level of 20 and a thread concurrency of 24000 this seemed to have worked great for the first week and a half until the stratum change happened, now i have a stalerate of
15m Hashrate   15m Stalerate
2.21 MH/s              2.74%

is this a good number, the stale rate i see jumping all over clear up to 7%

i tried dropping the intensity level down to 17 and my hash rate stayed the same but my "Bitcoins earned (not yet sent): 0.00370838", stopped increasing as fast as it does with the 20.

the last two days i have gone from earning an average of 0.015 to less than 0.010, my most recent payout as you can see is .0079
