If a TD enters info on wind and rain, it will raise our awareness to take a closer look. But deciding whether or not rounds on the same layout are combined or rated separately has become a mostly automated process using the actual numbers produced. Where it can come into play is on tee time rounds where we might not break out different time segments during the day to check the numbers unless we hear that the winds were significantly different between morning and afternoon.
BTW, adding rain alone without wind has not been shown to impact SSA. The theory is that players throw more conservatively and their average scores don't seem to change.
