True dat … and the reason is because neither I nor the authors have much data on evaporation. The authors fill that gap with models. Me, that’s not my style. Instead, I follow the lead of Robert Heinlein, who said:
“What are the facts? Again and again and again – what are the facts? Shun wishful thinking, ignore divine revelation, forget what “the stars foretell,” avoid opinion, care not what the neighbors think, never mind the unguessable “verdict of history” – what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your single clue. Get the facts!”
