128 and 256 sec averages are 0 for me, but 22.5 minutes is showing correctly.
estimated change +0.0. not a lot, just 400 GH, but still...
Reward system failsafed last night when my new code didn't respond to a query from it quickly enough. Sorry about that. As always, not really an issue... just lags stats until it catches up, which shouldn't be too long.
The 128 and 256 second numbers come from the reward system, assuming it's running. If it failsafes then those numbers get frozen in time.
The other numbers the stats build from scratch using the webserver copy of the raw share submission database, so generally those will be working if the stats are up and running.
