How much of that do you need to negate ratter vs subpar? For me (and I obviously get less than you) 30 is subpar but the bottom of non ratter. Anything under is a rat. To me you can only use ratter in the worst winters. And that should stand since I started the use of the term which is variation of “this winter blows dead rats” which we shortened to ratter. The blows dead rats term came from this guy in college who would say things like “this blows dead rats”. I know you probably remember all of this but we have a ton of posters who weren’t around when we started it 15-20 years ago.
