I had a singles practice yesterday. It's an indoor carpet court.
Here's how I put cushions around the device. It doesn't look neat but it works. I'll find a way not to cover the heat sink next time.

The court calibration was a big problem. It took more than 10 attempts. Once it found the court, it got much faster, like in 3 or 4 attempts. But the calibration screen started showing a picture of some other court, obviously the one in the sample video. So I couldn't tell if the green lines were aligned correctly.
I had all the signals on, so I could tell if the device was catching the shots properly. I guess more than 95% of the shots are called. It misses out calls more often than in calls. There were close shots on the baseline. It missed half of those calls. It was disappointing because that's where we want calls. Calls made on lines were almost correct. I can't review it because the video is lost.
Yes, the video file of the main session got broken. It's lost. I expected to watch point replays but I can't. It's a pity.
Here's the chart of shot placement. I am ElMago and the hitting partner is a coach. We only had cross court rallies. You can tell how consistent he is and I'm not. My shots are evenly scattered in a wide area but the coach is hitting back to the smaller spot.

Edit: I changed the images to simple links. Hope this works.
