Great job, Pete. Not anyone would address such a painstaking statistical analysis. The results are quite interesting.
I haven't seen the Jones and Datlow anthologies yet, and usually I don't agree with most of their choices

. I'm currently reading Guran's hefty Year's Best and I must say her selection is much more eclectic - I'm not saying that is better....
Hopefully none of those commendable Year's Best volumes will get Awards anymore (as in the past). I believe it's unfair to get awards just for picking up the "best" stories from other editors' anthologies....
