I now have a score for each of my stories.
When I resumed posting this last time, about 40% of my stories had scores. The others had been on the site longer than the grading system had been in place.
As of the time I downloaded the scores, I had 125 stories listed on the site. (One, now two, had been removed, but they are still on my list.)
(Probably this was a misreading of the situation. The site tells an author every vote. It doesn't report averages until there are at least 15 -- ? They report 16, and they don't report 13 -- votes on a story. I probably looked at different lists when I got those figures.)
That allows a simple division of my stories into 5 sets of 25 apiece, from most popular to least popular.
I note that 11 of my 23 Brennan stories (For...) are among the 25 most popular. (11 of the top 22, for that matter.)
The Brennan stories are each intended to stand alone, but they are probably more satisfying if read in order, starting from _Forever_.
