Here's why I think so.

White 314 loses 6% ????? Well, Black is considered to be ahead at this point, so that may just be the win rate approaching 100%. But that underscores the problem of using consecutive win rate estimates to indicate mistakes.

White 310 loses more than 3% ????? Here there is no excuse that Black is ahead. even after White 310 Black is estimated to be ahead.

White 302 gains 1/3 pt. (I am using territory scoring.) Is this a mistake at area scoring? Possibly, depending upon the ko fight. At territory scoring canonical play is for White to take the 1/2 pt. ambiguous sente on the top (White 304) and then take the 1/2 pt. gote at 303. Then Black can take the ko at 302, but White has a local ko threat. (Edit: I have looked at the ko fight. Black is komaster, but I don't think he has enough ko threats to make White filling the ko superior.)

Black 301 gains 1/2 pt. It is miai with 303, but worse for ko threats. Canonical play is at 304, ambiguous 1/2 pt. reverse sente.

White 300 gains 1/2 pt. Again, canonical play is at 304.

White 298 gains 2/3 pt. (ambiguous reverse sente). Canonical play is at 299, gaining 3/4 pt.

White 294 (saving 2 stones) loses more than 1%, with White ahead?

Black 267 gains 3%????? With White ahead? Surely that indicates a previous misestimation.

White 256 loses 6%????? Even versus the variation? Really?
