Since I use lower multipliers for Gotenks, the gap I have for SS3 Goku and the Boo Arc top tiers isn't mind-blowingly big. With the scaling implied in the first two arcs of GT, I end with BoGT Goku being not too much stronger than Base Gotenks (post) by my numbers, so that's the furthest Redjic gets in DBZ imo.
