You think that these perturbations are different than the perturbation method of prediction described by the sources in the Wiki link? Interesting. However, and unfortunately, "I think that..." isn't very strong evidence. You should support your opinions. I encourage you to demonstrate yourself to be correct through references, sources or citations.
You also think that these predicted positions are the result of, or match with, an n-body simulation? Interesting again. If true, that is quite extraordinary. I can only encourage you once again to provide reference, source, or citation to strengthen your ideas and opinions.
