Robustness certificate
How much the hooked finger tolerates before its grasp fails: the object placed up to 3 mm off target, a shake while it is held and a sideways push. Every episode is deterministic: seed jitter is off, so each condition is exactly as stated.

Score: the mean over objects of each object's placement, shake and push pass rates. Tolerance: the largest error that held on every object, in both directions; not defined here because at least one object is not held even at 0 mm.
Placement error
Share of the 9 objects still held when the object sits off target by the given distance. 91 of 117 placement episodes held.

Every placement episode, object by object
Setting k is the controller setting used for that object. Each object gets the setting whose undisturbed grasp worked best, and every check on that object then uses it. A different setting can tolerate less.
