It’s not like 2.2 billion emperor Blackbeard himself was ever actually comparable to crocodile of all people in legit any way. It’s not like buggy or mihawk was significantly stronger either
If we go by the logic that crew’s boost bounty despite luffy and law’s post dressrosa and wano bounties it makes even less sense
Imo there’s no deeper reason other than bounty never reflect an accurate or 100% true representation of strength and danger. It just represents your known feats and achievements nothing more nothing less. Actually technically it could be lower when the world government wants to hide information like luffy beating Moria

the 2.2 billion bounty representing his rocky port incident feats
- Had no bounty pre marineford
- He definitely got a bounty post marineford tho probably not that big
- Yeah he played a role in raiding impel down, killing an already dying whitebeard, and ate the quake fruit but I don’t think any of that would raise him too much
- Especially after luffy only got 400 million for everything between sabaody and marineford
- The highest bounty of the impel down recruits lowkey might have boosted him more than marineford. Kinda like Kuzan boosted him
- Yeah he played a role in raiding impel down, killing an already dying whitebeard, and ate the quake fruit but I don’t think any of that would raise him too much
- Assuming his bounty wasn’t already already higher than Marco’s 1.374 billion he probably got a boost from the grudge war
- The Rocky port incident was most likely the reason he had the 2.2 billion. With him getting credit for taking down Ochoku and taking Hachinosu as his base
- Kuzan being known as an official member boosting his bounty to 3.996 billion. With them scaling teach using the past admiral as reference. Imo the same way the would have scaled him had he defeated him

But yeah it’s not like any of them separately were comparable to Blackbeard overall or that cross guild was comparable to the Blackbeard Pirates. It’s just their bounties being based on information known or at least believed by the world government

When it comes crocodile at least (….mihawk too) they likely do get some extra boost in bounty from things like
- Being in an emperor crew
- Cross guild unlike other emperor crews going straight up against the marines and by default world government
- Maybe even a boost for being past ex warlords or because they were used as the model for the seraphim
- I say that one because it would better explain Jinbe’s bounty too imo
- As for buggy crocodile but mainly mihawk raised his bounty and perceived strength plus leading an anti marine group
