pools give miners less variance on income, but "luck" doesn't change, and payments are, in the long run, slightly reduced because of pool fees.
both your points 1 and 2 are true.
no. it cant be both true. as you can see, im asking about pool`s code logic. specially to avoid such answers i was trying to write in pm @Epsylon3. but i have 0 Merit at this forum and cant do that. so im asking the pool developer here in this thread.
I don't see why not, please explain.
