Just a small thing I noticed, but maybe it's indicative of a larger issue. On my quad core machine (http://boincstats.com/stats/boinc_host_graph.php?pr=bo&id=4961830), the second top day is listed as 7732 on Jan 18, 2009. If you take a look at the graph of credit per day for the last 30 days though, it shows that total for Jan 21, 2009. Did some of the days get messed up somewhere?

EDIT: Seems my lappie (http://boincstats.com/stats/boinc_host_graph.php?pr=bo&id=5011312) suffers from something similar. All of the days in the table seem to be for the day before the corresponding column in the graph. Eg: that host's top day is listed as January 27, but the graph says January 28...
And just noticed now that the graph doesn't actually list today as the last column, but yesterday. With the dates moved over one, that puts the graph off two days from the table above.
Sorry, I'm not trying to add more work to your plate here Willy, just stuff I'm noticing.

Two weeks ago there were some problems with the server and I decided to skip the host update for a few days. This affects the 60day chart and the best days achieved in those days (for hosts only!).
