Reparsing data

[Shawn Willden]

Right, if you read the rest of my rambling, I think they're using the
per-sample "exertion level" -- which is derived by the computer from air
consumption -- and using that along with the total consumption to fake a
curve.

I do want to see if I can get that total consumption number imported into
subsurface.
