I'm still trying to figure out why some people had such a low payout from last Saturday, so I made a nice comparison :

As you can see, all miners have more or less the same hashrate. Yet they have a very different payout and remaining balances (for the immature/unechanged balances).
Some observations I made :
1)
It looks like the pool is using the unexchanged balance as a multiplier, i.e. to play with. The only ones having a decent payout or the miners that had a lot of unexchanged carried over from the day before (miners 2, 5 and 6). Note that the actual unexchanged balance remained the same at the end of the day. Don't know what to think of that..
2)
Some miners had part of their unexchanged balance changed to their balance just before the payout whilst others hadn't (miner 1 vs. miner 0). What gives?
3)
Miner 3 is a nice example of a miner that basically started the day with a clean slate. Yet it got a better deal than miner 0, even though its hash rate is lower. Huh?
As you may have guessed, miner 0 is me.. I changed from EU to US about halfway through Saturday as was recommended by the pool operator in this thread at the time.
I really don't understand what was going on last Saturday, but judging from the above comparison it doesn't look right to me.
I am worried that there are bugs in the system that are costing some miners their due payout. Also, if the pool is using the unexchanged balance as monopoly money to increase profits, fine - but why isn't this the same for everyone?

I've also tried to relate the graph for the pool as a whole to the individual miners. Somehow I would expect them to be very similar except for the scale :

Yet they do not look similar at all, except for the miners that got a 'regular' payout.
Anyone want to share his/her insights?
