Ok, I'm getting it now.

typical calcs have a fairly large margin of error, which is ok given their intended use
- the problem for us is that the inaccuracy increases as the size decreases
-> and there are many assumptions that must be made in the characterization of some of the bits and pieces

What if calculations aren't used, but the information is pulled from K coefficient tables. I've seen a ton of these tables around the net and you would think they were based on, and verified against real world data.
I would really like for this to be possible, as I think it could be a good "tool". If this thing is valid at the scales we are using, and WB, rad, and res head loss values could be integrated, would it be possible to integrate thermal data? I realize it wouldn't be dead nuts accurate, but it would allow you to see the relative effects of changing things around.
Here's a link to the entire page this spreadsheet is on.
