The original episode is HERE. (Bad Ear Day)
The siderun is easy to break down since the keys are really clear (it is animated on 1's)
Start with 01 for the highest position (then flipped in 07), the other key is 04 which is the squash and 'passing position'. These then have 2 inbetweens each, which can be a bit awkward, I would say 02 favours 01 and 05 favours 04.
The frontrun seemed to have been done on 2's, with 5 drawings per step, while the siderun has 6 per step. The arms just kind of swing from one side to the other when the foot changes, which I assume is to keep a clear silhouette and balance out the figure.
