I did not notice that you Early position and Middle position represented multiple seats, and so this is in fact FR. I also could not find the steal stat, and now see that it's 266% as much as the usual button PFR stat.

23/17 still seems nitty from the button, though. It's hard for me to comment on what your ATS "should" be since I don't really know about your games or your table selection therein. 42 ATS from the button is probably about where it should be if you everyone at every table you play at is a fish, but if that's the case then your SB ATS should definitely be quite a bit lower than 57%.
