An excellent point, that I either never knew or forgot. Another method of determining absolute value? Thank you.

Is that a misprint, I wonder? No need to wonder. If I put the 0.002419 figure out there it was indeed a typo. The correct constant, according to Bowditch, is 0.0002419. Plug variations of 0.002419 into Excel and it does not match the tabular values. So big-boy rules. If you did it, admit it. If you broke it, repair it. If you lost it, replace it. If it was not one of my posts, I wonder which text? Any help there? Bill
