Half annual is definitely worth of D. But you did get some pretty decent LES events. Nothing exceptional though, I'd rare your winter a D as well. You're like me, you want heavy snow rates.
F 2011-2012
A+ 2014-2015
You have to break 100" with a few good LES events to get into the Bs. As are reserved for 150"+ and big time LES events.
That's my grading system.
This year will be a B-/C depending on next few weeks.
