I'm not sure if my question is more philosophical or scientific in nature (maybe both). But I keep hearing people say "it's not how many golf balls you hit in a day, it's how much focus you put into each hit that counts" (or something like that). My response to that is, "how exactly can one quantify what quality focus is on the driving range?". So let me try to narrate a practice range session:
bag full of clubs
already loosened up (stretch etc)
pick out 5 balls
before hitting each ball, stand behind the ball, find your target line, grip your club comfortably, take an easy swing perpendicular to the target line
staying focused on the target line, approach the ball, staying behind at least 2 club head widths, take your proper posture and stance, and take 2 smooth practice swings, visualizing a smooth swing, perfect contact, and a desired flight path (fade, draw).
line up "on the ball" and take your swing
hit your 5 balls
grab 7/8 iron, repeat
grab 5/6 iron, repeat
grab 3/4 iron, repeat
grab fairway wood, repeat
grab driver, repeat
analyze any flaws you may have witnessed (beginning trajectory, flight path, launch angle, distance, accuracy), and go back through your club selection and focus on correcting those flaws.
go to the practice green with 5-10 balls and chip/putt using same method above.
so, is this quality practice? thoughts?
