Josuke 4 71.4% Combo with Assist (JOJOASBR)

I'm pretty sure I did a combo that did 77% damage but I can't remember the combination. For now, this is the best I can do. You can also combo from level 1 into level 2 with the Koichi assist, but you do less damage. Also the damage does not seem to be accurate or could be using decimals? I ended the HHA with 711 damage, so if the OTG did 2 damage, why is the final damage total 714?
