52 being when brook supposedly heard of a rookie named roger minus(-) 22 years since roger died equals(=) an estimated guess of 30 years of being a pirate

30 years of being a pirate Plus(+) estimated age in Rayleigh flash back of around 18 equals(=) around 48 years of age at the time of execution/death?

So if whitebeard was 72 at age of death we take 48 the age of Rogers death and plus(+) 20 years to show how close the age between roger and whitebeard would be if roger were still alive which equals(=) 68 which can further strengthen the thought that roger and whitebeard sailed the seas in the same era and around the same age

Meaning that it is very correct that Oda has done his math correctly and that I am great at math lol

Equations in order in case anyone got lost along the way 52-22=30 years of being pirate 30+18=48 age of death 48+20=68 his age if he was still alive
