I like to use a clock dial image to gauge distances.

I like to use a clock dial image to gauge distances. I get stock yardages taking the club back with lead arm parallel to ground, 9 o’clock then a little more to 10 and up to what one would consider to be a full swing then accelerate through to finish. Basically 50%, 75% then full. Word of caution, very rarely should you attempt to hit an all out wedge. For control and spin purposes it is best to keep it below full effort!
