For completeness of comparing like with like, here's Sumire's game with lz226 at 3300 playouts. Her big mistake hanging connect on right side did indeed go up to 20% in lz226 view. Interestingly with lz226's stronger analysis Oh Yujin's biggest mistake was almost as bad, -18% for q7 push: lz says it's much better to directly connect under at s6 because losing a liberty means if you do that next white gets b9 valuable move in sente for free, so Oh resisted that with the hane there first but then white got to capture that stone in sente for some nice eyeshape (as compensation black got more profit in the centre, and those cut weaknesses ended up eliciting Sumire's to make her biggest mistake, so on a human psychological level of making bad moves because you can predict it will encourage even worse moves from opponent maybe it was Oh Yujin's best move!). And in fact Sumire's prior move at r9 was almost as bad: p11 is better because it too is effectively sente for s6 but is much more useful on the outside fight for surrounding the 2 black stones.
