I was in the middle of drill D7 where the balls are throw slighly to forehand then backhand, when midway through the bucket, the targeting shifted about a foot to my right. The balls to my forehand and backhand were both to my forehand. I moved about a foot to my right and that made the balls again to my forehand and backhand but I wasn't standing in the center of the court anymore. The app still showing the balls should be going just right and left of center but the machine somehow wasn't doing that.
ETA-- May have found the problem- ball stuck in the back of the machine.
