I've been a bit wary of the percentages and the payouts announced in total... They never add up.
There have been times when I held over 50% of the pool's hashrate, and got less than 30% of the payout that crackfoo announced in this thread.
Still pays more than mining BTC... But there's something wrong.
Going by the hashrate is not going to add up usually. This is especially true when A) coins found near the end of the shift and more so if they take a really long time to confirm and B) you pool hop. So, SHA for example. The most profitable coins take 4-5 hours to confirm. Sometimes longer. So if the pool was mining those coins say, for the last 5-6 hours at the end of a shift, only a few of them would get calculated in that shift, but may not actually pay you until the next shift. Since the exchange then also takes several hours to confirm. So there could potentially be ~4 hours of you mining not calculated into the shift, making your hashrate appear lower. But you'll see the effects of that if you stopped mining completely at the end of a shift. You'll most likely get payments for the next couple shifts even though you're not mining.
Take scrypt as another example. On my other pool since it has a lot more scrypt power, I added BTM. This had a pretty bad effect in the beginning because each block takes 24+ hours to confirm. So it appeared your speeds were slow and the profitability was low. However ~2 days later, profitability jumps and has been consistently higher than before now that the blocks are consistently rolling in. But this works since the speeds are consistent.
The pool is designed to favour loyal miners and discourage pool hoppers. So if you hop on and mine for 3 hours, when the pool is mining a less valuable coin, because the diff was too high & speeds were too low for the $$ ones , then you may not get as much as you thought.
