Here's another way of looking at some of the same data. I'm just showing histograms of OPRs between 2015 (the most skewed game) and 2014 (one of the least skewed games), normalized by standard deviation as Richard has done:

The difference between the games isn't as stark as I thought. Certainly there were more people with OPRs in the 0.5 to 1.5 SD range in 2014 than there are this year, but the curves are otherwise remarkably similar. That said, 1114's placement way out at 6.25 SD looks all the more impressive on this chart!
