curious 5-1 to play ROLLOUT

I didn't see the rollout-winner, bar/24 8/3. It has the advantage of minimizing shots (20) like 6/1* while not burying as deep. Four-ply analysis favors the hit, but in a full rollout 8/3 noses out the hitting play by .006 - well within the margin of error so call it a toss-up.

11/6 and 13/8 are ~.06 errors. Not terrible, but sub-optimal. Presumably this is because of the additional shots.
