so you are the same person i chat with last night?
Yes.
So if the pool as a whole have lower than normal "luck" when compared to the entire BTC mining community, I will get lower BTC if choose Proportional?
Not compared to the community. Luck should be measured by comparing average number of shares per block to current difficulty.
This is what I am understanding:
1. When the pool operates at normal to above normal luck:
PPS gives lower BTC, while proportional gives higher BTC.
2. When pool operates at normal to below normal luck:
PPS gives higher BTC, while proportional gives lower BTC.
Yes, but...
1) Luck is different for each round.
2) PPS income is the same in both cases.
Does how powerful a CPU or GPU change the above facts?
No.
