Puzzle metaphor for jump back

See my last post. I wrote that I thought the last piece of the puzzle for me was in the ankles. Stuck me that a Puzzle is a good metaphor for the jump back. I think there's all these different elements to it. All the teachers describe it differently and focus on different elements.

So, picture the jump back as one of those giant kids jigsaw puzzles. Big chunky wooden pieces. now I figure there might be what 9 or so pieces. thing is everyone starts the jigsaw differently and have dropped a different piece on the floor under the table (OK, getting carried away with this). We're all looking for a different last piece. The point is I think, is that we need all the pieces. We need the core and arm strength, we need the ability to shift our body weight, to lift up and swing, the jump back to plank from lolasana, the hand position, the tucking our legs up and in. etc how many is that? Eight, one more......drishti? OK, perhaps 12. Bandhas, Mulla and Uddiyana...is that one or two? maybe just one if your doing it right! And to really push the metaphor to breaking point, do we begin at the corners, the edges or start in the middle.
Your lists of proposed elements welcomed.
