Hello, I'm newbie here. I just tried this pool yesterday and already produced about 13-15 shares (I don't remember exactly) and then I turn off my miner and go to bed. This morning I saw my estimated reward become zero and nothing at my unconfirmed/confirmed, so what I've mined yesterday is totally useless?

Thanks.

This pool doesnt use Pay Per Share as a reward system, it uses a different system which is a bit difficult to explain as I dont completely understand it, but your reward will quickly drop to zero if you quit mining... This is to combat pool hopping. Leave your miner on through the end of round until a block is found, and you will be paid your reward for that block. Other pools have PPS as options, but the fee is always higher because of pool hoppers... Happy Mining!

I do not think it is very difficult. The value of each share you submit is calculated with the following formula:

score_share = exp(t/C)

where t is round duration in seconds, and C is a constant, currently 200. This means the value of each share is exponentially growing, so old share have significantly lower value compared to recent shares. So if you stop mining while others don't, your part of total pool score for that round will decrease exponentially. You can read the original post about this reward calculation method here: https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002.

Additionally, based on measurement I have found that each hour, t is reset to zero and your score is divided by exp(3600/C). This is probably to prevent an arithmetic overflow (see http://en.wikipedia.org/wiki/Arithmetic_overflow).

Hope this helps,

Do not quite understand.
If a connected mining shares in the last block. Gain much for little work.
This can cause miners privileged information may be in a pool (pps-pplns) 90% time. The other 10% Score in Slush.
Gaining much more than being 100% (pps-pplns) or 100% score.
There should be a rule, if you're not connected 1 minute before finding the block. Your reward will be divided by 3. This would avoid jumping miners knowing that the pool found a block.

Sorry my english

I am not sure I correctly understand what you are writing. But if I do: there is no way to predict when exactly a given block will be found by the pool. Looking at the characteristics of the CDF (https://mining.bitcoin.cz/stats/graphs/) you should ask yourself, after how many minutes in the round exactly a 'strategic miner' should join to realize any advantage.

Before starting your own assessment on the topic, it is worth to read what others have already shared regarding this reward calculation method:
