I am looking to keep stats for upcoming tennis tournament and I am wondering what would I have to track play by play to get good match statistics.
For example should I track every shot in the rally or maybe note down just where serve landed and where it was returned and at the end of the play note if it was winner, forced error or unforced error.
For example http://tennisabstract.com/ tracks every shot with additional modifiers like slice, drop-shot etc, along with other data. This is too much data for one person to track during a live match...so I am looking for most important metrics that would yield good match stats but would be feasible for a single person to manage during a match.
