I think that's easy to comprehend, to some extent anyway.
And you have to accellerate a little even to just keep the speed you know. (if you are not riding in vacuum, and non friction floor and hubs)

i'm pretty sure that unless you're racing at a world-class level the inertial difference between the two sizes is unnoticeable, so i'd say stick with what you have, and don't worry about it.
