Its a psy-op that makes miners choose pure PPS or DGM and thus takes luck/chance out of the equation.
I try not to look at PPS and DGM pool stat pages because seeing all those uber low payouts gives me a headache.
Do try to learn a little about reward methods. Nothing in the sentence above makes any sense at all.
What doesn't make sense is why you seem to think that low block payouts are a good thing for miners.
Block payout =/> 25 BTC = good
Block payout < 25 BTC = bad and waaaay to common with the previously mentioned payment methods.
Or, here is a little of what I like to call.. experience
. I earned 7.23889297 BTC in approx 48 days. Or.. 0.15081027020833333333333333333333 BTC/ day.
During that time, my hashrate grew from 1260 to 2250 mhash/s and would have averaged 0.11 - 0.12 BTC per day with pure PPS. It stayed roughly the same b/c my hashrate increases kept pace with the difficulty jumps.
The DGM payouts would have been laughable as several of those rounds took 1 day or less.
What tangible info/ data do you have on these matters ??
