(edit the 4x20+10 is similarly just 90)

I can let you get away with the first part about 4x20 just becoming the word for 80, but with this one, you’re just fooling yourself and others.

If it were just another word for ninety, than ninety-two would be (4x20+10)+2 instead of 4x20+12 And it works that way up to 96.

Just stop making excuses and own the weirdness.
