"You're definitely hitting the ball on the upswing". Have you verified this by tape or launch monitor?

What driver are you hitting? Roll on most drivers make it so that only the dead center of the face is true loft. Higher is higher lofted, lower is lower lofted. Amazing but true.

At a 225 yard average, your contact must be spotty at best (ie missing the sweetspot); OR your swing speed is very slow. Speaking of which, what is your swingspeed (measured)?

A good fitting will go a long way to maximizing your distance.
