Bounties are based on one's threat level. Major part of that is one's actions, especially defeating someone strong.
We all understand that Luffy's bounty should be higher because we know some of his feats that weren't known by the Marines, such as defeating Enel. If the Marine doesn't know about an info, it won't be included in one's threat level, thus lowering one's bounty. Chopper is the easiest example.
So, what are Zoro's equivalents? Which Zoro's feats? How high his bounty should be?
