Star signs are listed in the art book along with the other character statistics, they're canonical.

Your edit was an estimation, mathematically correct or not, it's a speculative estimation based on the real Junko when Junko A.I. is an avatar, not the real Junko. The figure in the chest size box was actually stated in-game, to calculate other vitals based on it is speculative and assumes Junko A.I. is identical to the real Junko.
