The burden of proof is on you to prove prime Roger/WB beat prime Chinjao something that never happened in the manga. Bounty is irrelevant to strength. 1.042 b berries Shanks>>>>1.32 b berries Queen.
The fact that you're still using bounty shows how desperate you are.
Garp is the only person who beat prime Chinjao.
Why databook/manga never shows Roger/WB beat prime Chinjao if they indeed beat him? Should not it be easy for them to do it since Chinjao crews were fodders? Unless Chinjao was strong enough to keep up with Roger/WB to make up for the lack of fighting strength of his crews.
