>>5817309>>5817311>>5817317Glad you're asking.
Here's the probability scale detail...
My reasonning was that last system was quite good. New scale is decreasing the amount of "Handicapping" and "partial progress" for two many time "Really good" and "Critically good" progress.
I liked the previous system and wanted to give you better odds, although still reflecting the harsh environment chosen (large, frigid, jagged)
