Jango’s CG bounty is 1,000,000 while his pirate bounty was 9,000,000
If Akainu was a pirate his bounty would be 5,000,000,000 x 9 =45,000,000,000
The Admirals would have 27 billion berry bounties as pirates
With Garp, we already know the Hero title multiplies your bounty by 5. A Marine HQ Captain’s bounty is 100,000,000 but Koby has the Hero title so his bounty is 500,000,000
This means Garp’s uninflated CG bounty is 600,000,000 and his real pirate bounty is 4,500,000,000
So Garp’s Pirate bounty is actually very close to Kaido but far, far, far from Admiral level, which puts Garp roughly at fruitless Admiral tier power which is exactly how Papa Lee has scaled him since Hachinosu. The math checks.
