Yes, but I won't be able to take advantage of Lloyd's generosity to make wall measurements until next Friday, and I was hoping to get an idea before then. Plus, as a former* engineering nerd, I wanted to have a little fun playing with the numbers.

*That I screwed up the calculation illustrates why the word "former" is used in conjunction with the word "engineering" in the previous paragraph. And, I did find an error so ignore the previous number. I won't post my new results until I have gone over it a few times.
