Granted, I'll be the first to admit that I'm not the sharpest tool in the shed, but could someone explain to me why within our 2016 block range between difficulty retargets, we have some blocks at 1777774 and some at 1779164?

This is the first time I've seen a difficulty change/difference during a 2016 block range.

Did I miss something?

Cheers,
Kermee

EDIT: bitcoind still shows 1777774.48200146, and all the latest blocks solved still shows 1777774.48200146... But http://blockexplorer.com/q/getdifficulty ...
