Timed Matches have been added to Squash Scorer and Squash Scorer Plus as of Version 2.12.
A timed match is one where there are a number of timed playing periods and between each playing period is a rest period. The score can be accumulated throughout the entire match (Carry over score) so that each player has a grand total at the end or the Squash Scorer supports the idea of timed games where each timed game is a game in its own right with its own score. The winner would be the one with the most games.
The timed setup screen looks like the following
The Carry over score checkbox determines whether each timed period is to be treated as a game in its own right or whether the score should be carried over from each timed period to the next giving a single grand total at the end. The Carry over score cannot be changed once a timed match is in progress. Start a new match to enable it again.
You can use the Add Period button to add an additional period. The above example shows two 10 minute playing periods with a 1 and a half minute break period between them. Again, the add period button cannot be changed once a timed match is in progress. Start a new match to enable it again.
You can edit any of the values for longer or shorter playing periods or longer or shorter breaks. Changes will be saved when you leave the screen.
