Mmm, then it makes even more sense as for why Mihawk is a fraud.
Garp vs Chinjao fights are implied to be a single clash fight where Garp was trying to win with in a contest of power against Chinjao's drill. It wasnt a proper fight actually.
So with Roger could have been the same.
Remember that Chinjao strongest attack is way above his overall lvl, like King Elizabello. So him having at his Prime a top1 attack in the verse wont be an outlier.
And seeing what is said about Shanks and Mihawk, Shanks mostly focused on trying to beat Mihawk in swordsmanship.
