The remaining ball is your average (actually the mathematical median, but let's not digress - golf should be fun). Now go back and try the same pitch shot from a tight lie and see if your "average" is the same.
Hit chip shots, pitch shots, lob shots, and bunker shots, all using the 11-Ball Drill to determine which shots are your strongest, and which are your weakest. In this way, you can identify the shots you need to work on, and thus determine where your time will be best spent in your short game practice.
