Those problems are not easy and quite atypical with respect to eye
analysis, so I'm somewhat surprised it doesn't get an even lower
number. Maybe some of the test cases it gets right are mostly tactical
reading? Which problem does it get completely right?
On a related note I have entered problems from
http://www.hitachi.co.jp/Sp/tsumego/igohpe.htm, so far up to number
244. Out of 589 owl test cases it passes 207, and out of 102 semeai
tests it passes 51.
