... will be good to get a baseline.
You'll get measurable improvement.
Oh, FWIW, my coach gave me the tip to use a towel as the landing zone (ie don't worry about roll out). So you can do the shorter chips, pitch stuff in a back yard, or open area near a sports field. (ie you don't need a chipping green). I use 2 towels, a large beach towel and a smaller golf towel on top of the beach towel to "mark" the landing zones.
Yes, this means you don't get a chance to hole a ball, but, it focuses you on the landing zone. So, when on course, you know your distances to a landing spot, and then work out what or where that is based upon the undulations and speed of the green you are playing at that time. Watch the pros on TV and you'll see them talking with their caddy about where they want to land the ball to get it to roll and finish near the hole. Since we can't practise every possible speed, break, combo etc. we need to focus our practise on a landing zone (ie the towels.)
Trick too, record the result of each shot after each shot. So, chip a ball, write down result. Chip another. This means you practice your routine to take each shot, slows down the rapid fire chip chip chip and focuses the mind to be more like on course conditions. There is no sense in hitting shot after shot UNLESS you are trying to groove a change, or LEARN a specific technique. Once technique known, it's about use, execution, practise in as close to on course condition as possible. Hence, one shot at a time.
And, practicse with the same type of ball you would use on course. You want to learn the feel, response, flight, spin etc. of the ball you play on course. No sense learning a hard low spin ball in practise to only then use a soft higher spinning ball on course and find the distance is different to what you practised.
I carry 10 of my game type balls with my clubs. I can pull up at a grassed area on the way home from work, grab my golf towel, pace of X distance and hit to my "target". I use a scorecard to record each shot, after 10, I move towel to another distance, maybe add 5m, then do same. Do that for about 1/2 hr, and I've usually hit around 70 / 80 shots.
Every range session at a practise facility I'll do at least 50 short game chips, and putting. I use it to break up the range session.
As others posted, 1/3 long game, 2/3 short game for your overall practice time and you'll find a lot of in course improvement.
