I don't have the ability to resolve the fact that he can't upload to bwchart.teamliquid.net--hopefully someone who does will be able to help soon

Hi, I still dont have any idea how to update bwchart.com, so here is a new version. I fixed a few bugs, added smooth curves, and a new chart called "Map Coverage". It tells you two things:
1-how much percentage of the map you have buildings on (it doesnt care about buildings that were destroyed, of course)
2-how much percentage of the map you are moving units on (moving=move or attack command)
Those curves work on a 8x8 grid placed over the map, whatever the size of the map. So it's a rough percentage, but it's good enough.
The first curve is a growing curve, like resources, because we dont know if buildings were destroyed.
The second curve is more like APM, because we consider unit movements only. To see that curve you need to check the "Units" check box. Also you can set the curve style (flat, dynamic, etc).
It's quite fascinating to see that on some pro replays, guys are sometimes moving units on almost 50% of the map. Considering a lot of the map is not even usable to place units (cliffs, water, rocks, etc), 50% is impressive.
Too bad I dont have my site on to explain how the computation of the curve is working.
Cheers

Snapshot showing "Map Coverage" curves and the animated map at a moment where XiaOzl seems to be moving his armies all over the place, while GoOdy is adding buildings in many places too. You can see all the blue dots on the map where XiaOzl is moving units, which corresponds to the peak in his red curve:
