OK so that is what happens to block 18290. It looks like you were mining only first 3 minutes of that block. So this is normal. But I don't get it why you got double from block 18291 since you didn't increase hashes... Did you change anything? The only thing I can think of that could be is a difficulty error in a score system and you change it from 2 to 1. But I guess someone would report that already... Looks really strange...

I haven't changed anything. so it's kind of confusing. Also, I'm on difficulty 6

Losing most of my reward for a short disconnect seems to be very unfair in my opinion. I would really appreciate if slush would explain what happened.

This is the way the scoring method works in order to prevent pool hopping. As the round goes on, shares from earlier in the round have less and less value until they are worth absolutely nothing, so if you only work for the beginning of the round and then disconnect, it is possible to get 0 reward even though you have submitted shares.

Read up on the "Slush method" of scoring for more detail

This is not a little unfair?
Why is bad when the worker recvive the reward what they shared has? I mean the block value is 25 BTC and we have total X shares, and when u have Y shared then u become this reward. ((25/X)*Y)
Why is that bad?
Please anyone explain me the score based pay system, i dont understand why is that good for all?!

Because it has been mathematically proven that to improve personal gain (in cost of everyone else in the pool), you should hop into another pool when pool's CDF is around 43.5%
This is why theres this score system (also pplns, dgm, etc...)

It means that with optimal strategy it is possible to
gain on average 28% of ones hashrate by switching from the pool after 43.5%
of the current difficulty number of shares have been contributed.
