Thanks for the calculator.

I started the client about 12 hours ago and found 2 blocks so far on an old poweredge 1950 I had sitting in a datacenter. The getmininfinfo reads:

{
    "blocks" : 68380,
    "chainspermin" : 3,
    "chainsperday" : 5.62366477,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "difficulty" : 8.99369812,
    "errors" : "",
    "generate" : true,
    "genproclimit" : 4,
    "primespersec" : 771,
    "pooledtx" : 0,
    "sieveextensions" : 9,
    "sievepercentage" : 10,
    "sievesize" : 1000000,
    "testnet" : false
}

The calculator said ~24days to find a block. Even with the 2 or 3x speed of now, am I just super lucky or am I missing something. Is the chainsperday per each thread by any chance?
