I have problems with this block. It is impossible that I have this reward from these shares:

No, it's not impossible. You have a low hashrate on a very long round.



less then 2 hours is NOT a very long round and with 157 shares in that less than 2 hours it should be higher given the .21733124 transaction fees added to the 25 for the block.
I have a similar issue regarding a few blocks, since the DDoS ' recovery ' I have managed to get a GPU ( getting out of CPU mining ) and of a total 39 confirmed my side i get the following

32 out of 39 isn't bad and it still isn't acurate as the difference isn't being reported my side as stale/NMC or Other.
I reformatted and pointed out the block with 3+ BTC fee in this group.
Still haven't heard from Slush if the ' missing ' shares are NMC or not and there is no NMC earnings listed for me at https://mining.bitcoin.cz/stats/nmc/ in spite of the getwork I did during the DDoS attack ( stratum couldn't connect, getwork could at times and would try to connect at least )
With my paranoia regarding network security, I would have reloaded the scripts for calculating shares, etc just in case the one that managed admin access dropped a few logic bombs... skimmers, etc.  things that would not get noticed until alot of people were missing their ' 1/4 cent per transaction ' ( or equivalent, if ya don't get the quarter cent ref, watch the superman movie with Richard Prior and see how fast it adds up ) with all the weird variances, ' missing ' shares there is room to suspect we have the system still funding the attacker with out our permission/knowledge.

Sorry in advance Slush, there is work to do to see if I am wrong ( and I hope for the pools sake I am )
