I'm pretty sure that was not his strongest attack ever, considering his old age, grave war wounds, holes in the stomach included...along the fact that he could just freaking destroy all of Marineford in one blow, he didn't do it! It's obvious that he didn't do it, because his entire family was there fighting along him. If not for his crew and allies and not for Ace, he could've been able to sink Marineford to the bottom of the Grand Line with one Punch!
