Hello

Have a question.

What should I consider when chosing a mining pool?. I have a S7 B2 on its way to my house. It should be delivered on thursday and this is my first miner.

I have been reading about the different methods each pool work (PPS, PPLNS, DGM, SMPPS, etc...) and also we can find several pools on each method. Which method and which pool do you think work better and why? If two given pools work on PPS for example, how is that possible that one of them could have their luck on "-8%" (just saying something), I thought statiscally both of them should be "the same thing" (of course according to their each mining total power)

Do they have any trick I should take care of?

Is there anyway to measure efficiency of each mining pool without having to test each pool for several hours or days?

Thank you
