Chaplin Skating in the Rink

In the film "the Rink", my favorite of the 4 shorts, Chaplin performs one stunt after another in long shots from a stationary camera.
The skating scene was amazing. He seemed suspended from a string at times, and i was impressed by the choreography. I wonder how much time he dedicated to those moves. Uncut, clearly stylized skating moves Fred Astaire could never have done better with his dancing. One of the finest examples of a continuous "action" scene I've seen.
