S-F, HSPF is a seasonal COP, it's supposed to be indicative of an average COP over the season, accounting for variable performance depending on outdoor air temperatures. Of course, every region has its own outdoor temp profile, hence that spreadsheet's adjusted HSPF values. I'm just questioning how accurate those adjustments are.
