Thanks @Acinonyx!! “He did the math” 
Are we still talking the db leaderboard here?
Not always the case if, say, a station has a very limiting horizon. (such as the vertical yagi test) - this scenario also goes against the “Maximum elevation” modifier.
So, I’m not sure if we should make assumptions about difficulty, as one station may be more successful at certain parameters than another, and visa versa (especially when comparing, say, one fixed station against another).??
Success rate and rarity of the data, for sure!!
