This is an interesting discussion. Yes, it is time to have a universal spreadsheet for the calculations. I have seen several measures use ones they developed.
I would hope our Certifiers go over the numbers and application. I know our application for certification has changed to make it easier for the Certifier to fill in the certificate. That is the present applications order matches the lines to fill in on the certificate.
Even if there is a specific PDF/excel form for the numbers, one still has to do the numbers while measuring. However, maybe they have this information built into a device to get all the numbers.
Lastly, this reminds me of how things have changed. Go to a store and see if the cashier can give you change without their register doing it. I was a HS teacher and over the years I saw many changes with our students using calculators that did all for them. As AP Calculus teacher, on the AP test there was a section that one had to show their work without a calculator. I really don't like that we keep making things easier.
