Practice two ways…1) fundamentals and new or flawed swing moves. These are things that we want to imbed (improperly called muscle memory) and imbedding comes from repetition of correct moves. …2) transfer practice for playing , which means one club/one shot. Just like on the course you never hit the same club twice(except for mistakes). I tell my students to have three targets on the rangers help “create” different shots. For better players learn to shape shots ( fade/draw/high/ low).
Note: putting with just one ball for distance putting will help you judge distance and relay that information to your body more accurately. Putting with multiple balls sets you up to miss due to message conflict.
