Journeyman Pro
I'm not so sure about his claim that it takes only ten minutes, though. Think about it. Ten minutes means ten swings a minute, giving you six seconds for each swing, without taking a break whatsoever. No time for a decent setup, aiming or stopping to analyse what you have just done. That's exactly like getting a big basket of balls on the range and just bashing that away without going through your pre-shot routine etc. which is exactly what every pro tells you not to do, because it just grooves your mistakes instead of develop a better swing.
