You know that iq only goes up to 200 right? Its a scale not a pure number , and its desinged to cap at 200, saying someone has 220 iq is like saying a phone has 120% battery. Its simply doesnt work like that.
just wanna say that a person of that iq would never worry about a raise and it would make the plot under a lot of scrutiny by the readers make it harder to be appreciated.
