Are you using a vive still? Maybe the offsets are different for Index and other lighthouse HMDs.
Actually I remembered that my vive had a problem, the hdmi part of the 3 in 1 long cable isn't working. I can get the headset to work if I snake a hdmi cable in there so I know it's just the cable. But I remembered that I had a Pimax HMD and that also works on lighthouse so I've been using it.
I don't really think the headset should matter that much as the values should still come out the same but I could be wrong. But the room setup may affect it, are you using a room setup or like a sitting mode or something else?
There is a variable I'm using that is for standing and the other options are for sitting or raw and uncalibrated. I think I thought standing would work for a normal room setup so chose that.
When I save coords, they replay as upside down and in the floor.
If you save the coords, then replay them and then save them again while replaying. And then replay that save, is it still printing out the same coords on is it changing around?
Probably best to open two cmd prompts and run the commands so you can see all the outputs.
Also you can use OVIE offsets to try to do the correction, I found you can change the numbers by typing them in so that saves pressing the + / - buttons
