'Clock face method' Pitching question

If you're going to try it, my tip would be to try it without aiming at a target, so go to your practice green and hit in the opposite direction. We get attracted to targets so if you are hitting towards a flag you may compromise results. The idea is to find out how far the ball goes with a certain swing length and club and then when you are that distance play that shot to avoid the need for compensation.
Hit 10 decent shots (discard any fats / thins...) you don't want to allow for bad shots, you want to know how far that swing will travel. Practice to remove those errant shots. Rinse and repeat with different clubs, different swing lengths, different grip positions...If you're thinking of going the Pelz way he talks of synchronsied turn not involving coil to aid distance control, this takes a bit of practice before this comes (it did for me).

Their's basically 2 ways of controlling distance swing length and speed of your pivot.

This way is pretty simple, their's nothing stopping you modifying anything to achieve a different ball flight if you wished, but it's based around simplicity, consistency and repeat-ability.

It doesn't need to be dead on 7:30, 9 or 10:30 it's your feeling of it (most people go back further than they think)

You may find yourself struggling with certain swing lengths (people often the shorter ones harder, so don't select them unless you have to - change club instead)

You can combine it with gripping down to cover even more distances / trajectories.
