Well, all I can say is, facts are proving you wrong by the fact that Mihawk STILL IS WSS
No matter how you people try to spin it, Shanks, Fuji and others fall into that category. You can try to twist it by saying "strength as in brute force only" or whatever excuse you can come up with
Mihawk is the undisputed WSS and aknowledged by ALL CHARACTERS inside the series. That is a FACT
Also, Shichibukai is not a LEVEL. Buggy is not same level as Law who is not same level as Mingo who is not same level as Mihawk. So, just because a person title is a shichibukai, not a yonko, doesn't mean shit when Mihawk's title includes Shanks and Fuji
You can ignore it, and keep arguing and using all kinds of time-frame analysis. End of the story, Mihawk's title is aknowledged by ALLLLLLLL characters in the series. We the readers just love to spin it around and twist it for our bias judgement.
Mihawk can sit idly by, only eating onigiri, and farming and getting lewd with Perona, at the end of the day Mihawk has the title and Shanks does NOT
