distribution of PR

Timothy, Bob and Bill, Do we have any interesting data on the distribution of PR generally and the distribution of PR under particular conditions? Is that a necessary first step to any kind of analysis? As long as we are forming hypotheses before gathering data, here are a few more questions to ponder.

I have to think back a long way to lectures I didn't fully understand, but it is clear to me that PRs are one-tailed. If I look at my own PRs, when there are outliers, there is a lot more room for them on the up side and it takes pretty special conditions to turn out a PR significantly lower than average. But I wonder if the shape of the tail is very different for Giants than for more recreational players like myself. What other conditions the shape of the data, and is there a way to control for those? For example, I know that my PR is much higher online because I play too fast. But I don't know if the shape of the distribution is different. I know that I make particular kinds of errors in a low-dollar local chouette that I won't make at a weekend tournament. Does that mean that these samples shouldn't be combined? Too many questions. I'm going back to sleep.
