From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You went way too HAM on this lol.
If you want to test if the latency is in the software of Wayland itself, you can just create a software emulated HID input device that generates the motion, and a script that registers movement and click. The control being the emulated HID device, and the variable being the different compositor. Start a script that moves for a predetermined amount of time and click, and just record the difference. It should perform the same way each and every time, unless something is slowing it down, no?
The problem with this is more so that I would still have to record this "IRL", as recording it in software is just... meh (I mean, I could try), and I just don't have the equipment for that (I demonstrated as much there), so I will probably end up doing the Pico + light sensor thing as described there. Should be more reliable anyway (something very similar has been done already, and successfully), so... yeah, that.
