I can see some of it one tier higher or lower, but the general idea is more or less pretty spot on.
The only thing that catch my attention is Oden.
Only because he could read and write in poneglyph and has journal doesn't mean that he is sharp.
Imho, he is more like Luffy than Robin.
Even sometimes he was very naive to the point that he tried to burden everything on his shoulder.
Even Zoro who you put at "very dumb" is sharper and more calculated than Oden.
He show pretty good understanding and helicopter views in dire situation, which is a sign of sharpness.
Anw, great effort mate
