 Just wondering what happened,why block 13587 payout is so low.I'm mining about 2220 Mh.The payouts before and after are correct.

What pool?

Looks like Slush's pool (especially since that was the pool that recently mined its 13,587th block).

Are you familiar with the scoring system of Slush's Pool?  It gives a large weight to recently found shares, in an attempt to discourage miners from hopping pools (If you aren't familiar with pool hopping, it comes from an unintuitive bit of math that says that if you jump between several proportionally paid pools, always at the pool that most recently found a block, you can greatly increase your mining rate).

What this means is that after about 10 minutes or so of not mining your prior work is pretty much useless.  If your mining rigs had some sort of a connection problem or something like that just in the final few minutes of the round, you basically lost all of the work you had done up to that point.  Conversely, though, if you come in after a block has been going for an hour and mine for 10 minutes, at which point the block is found, you make profit almost as if you had been mining the whole round.  On average it works out.

There's also the fact that Slush's pool, despite the scoring system, is still heavily hopped.  The mining rate for the first 10 minutes of a block is almost double what it is after an hour.  It's possible that there were just a whole lot of miners that jumped on to that pool right at the end, but this is less likely, as it is the opposite of what most pool-hoppers do.

It is slushes pool,and my miners have been constant,not hopping.the block above and below are right,why only .0016 for 1:32:46 when the block before paid .0644 for 1:17:49?
