- He was 25 when he became a famous rookie
- He was 38 at lodestar and 39 during Rocks' destruction
- He got his disease at 49, which is 10 years after Rocks
These informations show just why Ace and Luffy's rise since the age of 17 is perceived as crazy
On the other hand, it shows as well that Roger had at least 10years to grow even stronger post-Rocks, the time where we probably got battles between Prime Roger and Prime Whitebeard before Oden's arrival
