Remember, if you have two significant figures, you have considerable 
uncertainty in the second digit. At a mass of 10% of the primary, that 
works out to an error of not more than 5% in year length. Considering 
that non-computerized system generation tools typically have uncertainty 
of more than 10% in the mass of the primary star, any errors caused by 
the superjovian are relatively minor.
