A few things:
1. Measuring payout over a period of 2 days on any non pay-per-share pool is not enough data to make any conclusions. (pool luck makes a big difference)
2. Rolling time doesn't have any effect on sending results. You have the same odds of finding a share either way. (and thus the payout is not affected)
3. The pool doesn't card if a share is from locally generated rolltime work or work sent by the server. Either way it will count the same.
4. If you still want disable the feature you can modify your URL to set maxtime:

But let me explain my thoughts again, because I think there is a uncertainty in my problem.
I work in Slush's Pool (bitcoin.cz). Because of pool hopping he implements in this pool a system, where older shares (from beginning of the round) has lower weight than newer shares, which demotivate cheater from switching between pools inside one round.
Matematically said, for every submitted share, pool perform:
score = score + exp(round_time/C)
So you will get relativly more BTC for
one round, when you send shares close to the moment, when the solution is found and the round ends.
When I now submit shares in longer distances because of X-Roll-NTime, then the probability is higher that "a lot of other workers" send shares after me and gets more and more points for a round. So I'am interested to send results close to the end of a round, even if it are less shares. I will get proportionally more points for it.
For me it seems to be beeter to send shares more often to increase the odd, to be close to the end of a round and to get more points relativly to the others. It is an exponential function with the time. You said in your second point correctly, the odds of finding a share is the same, but the points I get for the shares depends on the time when I send. This is the way I understood the payment in this special pool (current hashrate: 1430.657 Ghash/s).
With your fourth point you gave me an explanation how to disable the feature. And after some rounds today it
seems to be, that the average BTC for each round is higher, in each case closer together and the fluctuation in earnings per round seems smaller like yesterday. In any case, it feels like it.
So I'am happy now
, higher hashrate with Phoenix 2.0 and a higher average BTC for each round.
Thank you again for solving my problem!
