of course you can, you just have to enter it correctly. Normal set score needs 2 numbers but tiebreak set needs 3 numbers. The 3rd is the number of points of losing player in tiebreak. So if you need score 7-6 7-6 you can enter e.g. 7 6 3 7 6, which will result in score 7-6(3) 7-6(0). If you enter just 7 6 7 6 the final result will be 7-6(7) 6-0. Hope it's more clear now.
I'm not sure about that one, haven't figured out yet.
Maybe manutoo can tell how (if) that could be done. Also I'm not sure if it is possible to enter score with match tiebreak in the last set of doubles. Looks like the game engine doesn't have any special validity check for the entered score (aside for the mentioned tiebreak game)...
hey manutoo when i watch my male player lossing his match in the final of australian open in 5 sets. i could see when i click on the next week that the score was not correct he lose the last set 6-2 and i saw the 5 set score was : 6-2(0) ,he was not lose his set in tiebreak, i think that is a error in TEM game.
i think that the error is only at the australian open final of 5 set
if you mean the 5th set problem I have also reported it to manutoo so we are working on it. Only after posting my report I have noticed that you have reported it first here
