An engineer overthinks tennis in a daily journal.
The only reason that I was aware that Hawk-Eye Live was in use for this year’s WTT event is because it has failed to make a call on a couple of occasions. Those errors of omission were quickly overruled by the chair umpire. It made me wonder about the error rate of the Hawk-Eye system and how it works exactly.

In my junior development days, there were basically only two drills that the coaches used for conditioning. The first was to line the kids up on the outside of one of the doubles alleys and have us “run lines” which is essentially just a series of short sprints. The second was running some number of specified laps around the tennis center, or later when I was playing scholastic tennis the adjacent track around the football practice field.
As I was watching “Schroders Battle of the Brits” a couple of weeks ago, I noticed that Andy Murray was wearing what I assumed to be a back brace during one of his early matches. I was trying to figure out the exact nature of his new apparent ailment before I noticed that all the other players were also wearing the same device.
