Here it is in text form ... kind of hard to read without tables and graphs.

I am inclined to say "Interesting" but I can't so I will have to say "pretty" but what does the graph actually mean?*Originally posted by petrovitch***Haven't run RHP Player Stats in several months. Here's the latest update. Look at the web page for a table view of the stats.**

These dates were just random and not selected for any reason. Over time we can determine cycles, trends, and seasonal effects of the data.

Overall, not much change. The numbers are about the same. Roughly 35% are rated between 1200 and 1400. Almost 97% are below 1800. The average player is 1324. - 23 Sep '08 12:58

the median has been in 1280s for years as I remember, it seems to have increased recently...*Originally posted by petrovitch***This is only the second time I've posted the stats.

Overall, not much change. The numbers are about the same. - 23 Sep '08 13:08I don't know anything about RHP's internal numbers over time, but the statistics I've gathered in May and September show the median is unchanged (1303, 1305). I am not disputing what you have said; I'm just saying that my statistics are independent of RHP and simply draw from their data.
- 23 Sep '08 13:36 / 1 editI wonder how much of the distribution shape is caused by the rating system itself...

Edit - I mean, there are obvious ways that we can see that it has a strong impact but, for example, would a simple increase in the number of players (that start at 1200) be expected to lead to a shift in the median? - 23 Sep '08 13:51

a couple of years ago it was 1280, then 1281, then 1285, 1286... can't remember the exact times, but it seems now it's been more or less steadily climbing towards the average... you could probably find some of the older data by searching the forums. the average has been posted only once or twice (by chris I think), but median more often as it's so easy to find out.*Originally posted by petrovitch***I don't know anything about RHP's internal numbers over time, but the statistics I've gathered in May and September show the median is unchanged (1303, 1305).
