I have created another Hunter spreadsheet with a smaller scope. It calculates average noncrit and crit damage for ranged attacks, then provides a 'shot average.' Shot average being the result of weighting crit, hit, and miss rate.
The effects of Haste and shot rotation in general are purposefully left out. My goal was to provide a lightweight alternative, accurate within its limits. I also find the act of creating a class spreadsheet personally educational.

Plan to look more closely through Lactose and Cheeky's spreadsheets now that I have a better idea what choices and relationships are involved. I'm sure there's more to learn.
