Identical twins

My original title for this post was "A silly statistic". When I saw that my percentile for the MTT-R NLHE I played last night was exactly 50, I knew that was a rarity, so I decided to look into how many times that's happened. It turns out the answer is just five times, in 205 tournaments. It's silly to look for percentiles of exactly 50, since that immediately cuts out all the tournaments with an odd number of entrants. When you look at stat lines of the five tournaments, it's pretty clear why I changed the title:

percentile entries place paid hands     date

    0.5000      68    34   15   26  2017-07-11a
    0.5000      60    30   12   61  2017-08-29d
    0.5000      62    31   15   57  2017-10-17a
    0.5000      62    31   15   56  2017-11-01b

The last two on the list are close enough to each other statistically to qualify as identical twins :-)
