Hello Antoine,
I concur with your observations - I just have a couple of comments.
The many_body_fix spreadsheet has four iterations of the algorithm already hardwired in it, so that, from a user's view, it looks like a single calculation. Four iterations seem to be sufficient for convergence with any reasonable AP. I don't recall having to manually plug the first result back in as input because "d" in the yellow cell (D4) was never greater than 20 miles after the first pass.
We could also revisit the archives for Frank's posts on "rapid-fire fix" for additional information on this topic.
