I was limited for some of the reference lists in what I could quickly find as an IMDB list. Our top 100 displays a fairly good normal distribution, as would be naturally expected with a mean in the 60's. In fact, the most frequent year for us was 1974 and even with a weighted average, it falls in the 60's. CF top 100 does have one of the smallest spreads in values compared to the other lists, but our shortlist actually has the largest that I found! Also interesting is the radical change in the most frequent year from our shortlist -- 1946 -- to our final 100 -- 1974!
Note that our shortlist actually does not have a normal distribution, and that really only CF 100, CF 250, TSPDT 2017, and 1001 2CB4 display this nice quality. Oddly enough, S&S stays right on 1959/8 with every gauge of the year-bias.
Anyway, that's all the input I've got in me now... I'll let any interested parties pick out any other trends while I go eat

Also, I'd like to put in my own word of appreciation for TMDaines, since I used his IMDB lists for CF Shortlist and the 2017 TSPDT.
