David, it LEAPT AWAY from Jupiter, into what would be a broader ellipse, not the tighter eccentricity the JPL gave it after the leap away! I'v been posting this contradition in the Orbital Elements that JPL posted on June 27, 1996 for weeks now. Still no explaination, either.

Would that the newspapers that the public reads would report it that way. In fact, you don't KNOW that they repeat at all, much less in that time period. Nevertheless, the newspapers have consistently reported the party line, with NEVER any of the shoe shuffling you're exhibiting.
The fact is, it was 4,200 years during 1996 as that's what the ORBIT REQUIRED. I'm talking about the orbit that drew a line between the nova and what we're seeing now. Now the orbit has to fall in line with a REAL COMET, not a line drawn in the sky, and things are very, very different.
That's why it changed.
