The spreadsheet is a benefit of membership in the Disc Golf Course Designers group and is not publicly available.
Wind will increase the scoring average on a course but seems dicey to directly account for in a hole design SSA calculation. The Hole Forecaster determines baseline values without wind. However, if the designer wishes to account for it due to reliable wind speeds and direction on a property, they can adjust for that within the spreadsheet if they wish.
