make sure to zero out the extra fields beyond the number of sprockets needed
The spreadsheet calculates "Nspr" based on the number of spockets you enter (or it WOULD if you don't enter a number in by hand

You are correct however in that the tool has some ease of use issues.

P.S. I know of no rule of thumb that say the goal is to wrap 180 around each sprocket. I have no objections to 180 degrees of wrap, but many times I live with much less. I typically am more concerned with the number of teeth engaged than I am the wrap angle getting to 180. For what it is worth...
