[TML] The proper year length of a super jovian

This makes the length of year for a planet; based on WG.pgf, page 15, 2.1.1
"where a is the orbital distance in AU and m is the mass of the
primary, in solar masses. If the planet has significant mass compared
to the
star (like a large superjovian and a small red star or brown dwarf),
add the masses together. Result is in Earth standard years."

My question for all you space experts is what is meant by
"Significant" here? I am now using, significant is when the the mass
of the super is divided by the mass of the star and it is over 60%
I am thinking that this changes the year because the barycenter is no
longer in the center of the planet. Is that right? Also how would this
effect other planets with them?

Thoughts anyone?

Thanks,
Douglas E Knapp
