I'm not sure why you're counting the years of support for a version of the OS and not the years of support for a computer. The interesting thing is: if you bought a computer at year X, does it still receive updates at X+Y? There's loads of relatively young computers which can't upgrade to Windows 11 and therefore aren't supported anymore. That's the problem, not how long Windows 10 was supported.
