I'm not an engineer, but this sounds good to me.
The max x-wind is determined by the surface area of the rudder because that surface yaws the aircraft. However, the surface area of the rudder is not the only condition. It would also have to be based on max gross weight because the rudder must be able to yaw the mass of the aircraft.
This is why a 747 rudder the size of a cessna still only allows a max x-wind of 38 kts.
My .02 - but again, I'm just using logic, not any factual support
