Having added this position to my database, I also had a rollout cooking. Mine is sans Jacoby. Its result differs from the Jacoby rollout Nack made by about 5 millipoints. 3 or 4 may be typical for a “standard” early position, so this is in the ball park.

The GnuBg trunc, which mimics XGR++, did better than XGR++ itself in this position. Both it and the full 15k XG rollout have P trailing K by 31 millipoints. Interestingly, the GnuBg estimate for the absolute equity of K is worse than the one by XGR++. All of this assumes, of course, that the 15k rollout is better than both.
