Thanks! Great catch. However it is our intention to make less than the source of truth, which aligns with the spec.

Oops, I realized I just reverted all your edits as I make it fit what I believe to be correct, thus verifying that the original content is indeed correct. x <= y is equivalent to !(x > y), which is in turn equivalent to !(y < x).
