I will probably record a friend's match in a few days...How do you determine whether a shot was an unforced error? For example, what if the opposing player hits a drop shot, the other guy barely gets to it, then hits it out? Is that considered an unforced error? On the flip side, what if a player hits a good approach, hits a good volley which the opponent barely gets to , then that player dinks it over to the open court...Is that considered a winner? Or do they just record blatant winners/unforced errors as such and leave the rest of the shots alone?
