This isn't me (I wish I could do it like this!), but have a look:...
- he actively extends to get his feet to the ground quickly (he doesn't wait to land),
- he appears to do something like "down-unweighting" so he doesn't have to jump as high and waste time in the air.
- his heels don't seem to touch, and may not clear the line each time allowing smaller jumps,
- and he certainly doesn't jump all the way back to the center.
So it's not really jumping in and out as much as lifting your feet and touching. Mimicking these techniques I was able to come down from about 20 sec to 12 sec without much trouble. That last second has been trouble though...
Oh, OK, if you define "back to the middle" as "just inside the edge" then I should be able to pick up my time a fair amount. He's pretty quick, good job keeping his head still. That helped a lot. A video's worth.... (hmm, let's see, 10 seconds * 30 frames/second * 1000 words/frame...) ... 300,000 words.
Thank you very much. Off to give it a try.
