I don't know if I agree with that. Because last time I had COVID the line got lighter as I started to get better until it no longer appeared.
Sure. The darkness of the line does have a lot to do with the concentration of antigens. But there's also the issue with the antibodies that make the line dark where they do start to degrade.
When I had COVID I was constantly retesting, and it was really dark for my first positive and my second test (just in case it was a false positive).
