I honestly do not know what you have heard or completely understand, but the basic philosophy that we adhere to is to start as many series as possible on a yard line. If the ball is played within a series then you put the ball where it was downed. But for any long run or clear first down, we try to put the ball on a marker. It helps keep track of the starting point and any penalties that may take place. Near the GL we put the ball where it is downed because inches really matter than. No one cares were the ball is placed in the middle of the field an inch or two one way or another. Not sure that answers your question, but that is what we do in both HS and college when we have well marked field, which is becoming more common with the new turf fields.
