I practice all the time. But the range typically I only hit a few balls at. Maybe a small bucket when the swing is going well. When it is time for a swing change, I will grab a jumbo about 4 days a week and the buckets will gradually get smaller as the change kicks in. I won't play any golf during this time.
Short game is where I practice most of my time. We have a nice facility with a large green to chip and putt on. Fortunately, they are open until 10:30 so when the kids go to bed, I go up there. I putt, chip and try to push myself. I started doing a new game where I have to get up and down with three balls. There are four cups that stay in the light on the green so I use all four. I start with the easiest hole and get up and down then move to the next hole and get all the balls up and down.. if I miss one up and down on the second, third, or fourth then I have to go back to the first hole. So basically you have to get up and down 12 times in a row. I will be looking for a new drill now though as the second night of doing it I shot 1 under my first try and shot another 1 under my second try. I am trying to practice at the edge of my ability but either I got lucky or I need a new drill. I do think it is a great drill for my buddy who is an 8 handicap though.
I RARELY practice my driver. I will start more next year as it has become a weakness finally, but it has always been a strength. I try to play at least 36 holes per week too. All in all, I got it down to a 75 scoring average in TOURNAMENTS, not rec rounds so I am happy with that. My practice routine has shaved off 3 strokes from my previous scoring average last year which is the biggest improvement. Had my first bogey free round a couple of weeks ago. Biggest thing for me was learning how to play misses this year. Off the tee I am looking for a spot that will give me the largest margin for error. From that point, if I am in the rough 120+ out or in the fairway 160+ out I am aiming at the center of the green.
Swing changes coming soon though! Only way to compete with the web.com guys I play against in my favorite tourney of the year is to get a higher ball flight to stick it close on firm greens.
