I typically include a velocity session in most of my lessons where I will use radar on every pitch and tell the pitcher to let it fly, push the envelope. If a pitcher is overthrowing when she knows she's being 'gunned' then she needs to be exposed to it even more not less. I will also use radar on other pitches as a form of feedback. Knowledge of results (KR) is an integral part of motor skill acquisition whether it's radar readings or strike/ball ratio.
