Is there a name for that method? I use the term iterations, but perhaps there is a better name for it; there should be. I'm fairly sure this is required for all but 2-body models.

Apparently, only recently has there been effective mathematical work regarding chaos in orbital mechanics. Resonance in precession ratios has also come into play, though these are long period factors.

We know time flies, we just can't see its wings.
