It looks like the stats generate at different times. What time do they usually run?
All of the statistical reports are updated every 24 hours, usually between 2am and 4am PST. All of the bandwidth information is updated every 6 hours. If you wish to compare data from each statistics program you should only compare data that is at least 36 hours old to ensure that it has been updated and is providing the correct information. Please note these times are estimates, and are subject to change based on the amount of traffic on the server.
