Yes.

I just tried Seth's formula, and the result is much closer to "real" or "useable" or "practical" 
output voltage than the one I have been using for 50 years or so.

I do believe I have just now switched to Seth's formula for my power supply work from now 
on. :-)

Thank you, Seth.

I would like to know about "Shay's Curves" though....

One is never too old to learn something new and perhaps better or more accurate.
