Vex, I like your spreadsheet idea. I updated it to be more linear (for the easy addition of more data). You should be able to copy the formulas down to each new row.

Nah, engineering units aren't the issue. I just didn't know where you were pulling some numbers so I left it blank. Besides engineering numbers are master units; L, in, lb, kg, not slugs, g, etc (though I suppose in can easily be substituted for ft)

That looks a lot better than what I originally had in there. May I suggest you put the link in the first post so others can add their numbers if they desire (I'm planning on doing something similar with the db profiles when I get around to getting to it).
