No questions, but feedback for you from an engineer in a similar situation (late diagnosis), make sure you go back and get them to check for every other thing under the sun. You really don't want to dive into the ADHD side and find out it was something else (other things can masquerade as ADHD), so a good neuropsychologist is critical. And "body medicine", too, for example adrenal disorders. It's worth being extremely thorough at this point - you're off the standard path, embrace it.

Also, congratulations, once you figure it out your life is going to change for the better in a way you can't currently understand (literally, lacking the brain regions and/or development for it, take it from me), but the process can kinda suck a lot, so stick with it, it's worth it in the end, wherever you end up.

Would you mind sharing the test platform?

Have you got some fancy scroll thing for your blog? Something in my brain is noticing that scrolling feels smoother than your average site, though maybe im crazy.

Following through on the top comment, surely you realized when you decided to forgo the back half of the test that, had the program compensated for it, you were consciously leaning into the ADHD diagnosis, right?
