In order to improve my time management - I keep track of time I spend on every move during tournament games. Those get scribbled into score sheets by hand and then I enter them into the database by hand together with the moves themselves.
Do I ever look at them again? Not very often until now – having discovered how handy it is to look at this data in SCID score graph, so after converting values into the graph-friendly format, I can see my remaining time visually – from 100 minutes remaining on the clock to 0. I can see that my time took a drive on move 13 or so in a recent game I played.
Clicking on the dot on the graph – I can recall that I was trying to spend some time out of the opening – trying to find a plan, before playing 14… Qe7. Was it justified? Looking at the graph above – probably not.
