I'm not the man to do it but it would be interesting to take the daily number (let's say at 12 oclock every day) and then create a graph over the month. This way we'd have a visual aid and could use that graph for discussions in the future when people ask how either consoles did in a particular month. The monthly chart is a good indicator of who wins but a monthly graph would be a good indicator of what effect certain games had on sales and when their were slumps and spikes.
I suppose you could even do one for all the titles released that month too.
