Several of the four-arm-linkage lifts I saw this year only needed to span about 30 degrees of arc to pick up a game piece from the floor to quite a few feet off the floor, so 13 seconds per revolution would be a bit under 1 second. At these sorts of ratios, a CIM could compete for some jobs for which we would previously only have considered pneumatics.
