If you check figure 4, SF at depth 15 matches about 47% of the time which is lower than their NN. So quantitatively, SF isn’t amazing at move matching, and lower than the best NN at its relevant rating range (1900 -> 54%).

Qualitatively, SF is pretty unsatisfying as a model of a pro human because a lot of its moves are counterintuitive.
