Use a start-line rod and film to find your chip miss
Put a single rod on the intended line and aim to get the ball as close to it as possible; record the exercise with a phone on a tripod to identify the miss pattern. A miss to the right can indicate getting underneath it with the right shoulder moving low, while a pull to the left can indicate the clubface working and covering too much.
