I can't read the screenshot either. Posting text is better because it can be
read on any display.

But I can see that GR1 and GR2 have triple-digits in them.

Note that they are RATIOs not number of teeth.

So, if I have the motor shaft with a 15 tooth pulley to a 60 tooth pulley, then GR1 here
is 60/15 = 4. You enter 4 in the spreadsheet.
