kiawah island 1st hole is a good place to practice the green is really flat
ok your putter scale , set it for 30 feet find the middle of the scale and practice 15 foot putts, but don't hit him into the hole.when you max out your shots go back and start over again. if you do this in a practice mode remember to set the green speed or if you do a in a ranked round mode it will set the green speed for you.
good luck
keep it on the short grass
