Some kind of guide or something was used, because if not, why are are the individuals scores written so far below every line in the program? I can understand in doubles, so as not to write over the names or printed info, but in singles where there is plenty of space to write the score? Something is funny. Either way, it is a very cool program. I keep score as well, but do it in a way so I can see who scored what in each round of play. If you just write score all across the same post, you can't always tell how long the game went.
