Mt.Gox reports trading volume, but it looks like it's always "average per hour" volume:

This is the chart with the point showing the volume for the last half of March 20th.

This is the chart with the point showing the volume for the 3pm hour of March 20th.
I eyeballed the total volume for the last half and it seems to be about 70k. Divide that by 12 and you get just about what the first image shows. I haven't been able to verify this with any info on the site. Does Mt.Gox explain this anywhere and if so, where?
Thanks!
