Not necessarily correct!
Your bag is in the wrong place if the overall time involved is longer than it could/should be.
True - true. I decide the point I am likely to leave the green after putting that will minimise my walk to next tee, and I place my bag somewhere on or close to the path from that point to the next tee. The point I leave the green after putting may not be the point that defines the absolute minimum distance from green to next tee.
But it should be obvious to each and every one of us when we have left our bag in the wrong place since we will find ourselves getting to our bag and looking up to see our PPs reach the next tee
