Puzzeled by my sng stats

[Zelcious]

I'm a bit puzzeled by my 40 recent sng stats.
Here are the my finnishes:

1 9 7 1 3 3 1 2 5 5
9 1 1 1 10 1 2 3 7 5
5 4 5 5 7 5 4 5 5 6
5 3 8 2 3 1 1 5 6 5

9 first
3 second
5 third

+200$

ROI 50%
ITM 42.5%

What I find really strange is that I have 13 straight games without ITM in the middle. Isn't that extraordinary high ?
