It’s awesome they try to define those terms. But I wouldn’t call that well defined at all. https://www.lexology.com/library/detail.aspx?g=6a4c20dc-594d...

I would say that math is unambiguous.

Measurements are becoming more unambiguous. The accepted measurement of a kilogram equalling s Avogadro’s constant. Something like the number of silicon atoms in a 93mm sphere?

But the definitions of best and reasonable are only accepted based off precedent and we’ve seen in recent history precedent in law isn’t as reliable or defined as we may have thought.

Is there any language or any level of language that can remain defined across time and culture?

So long as legalese requires interpretation to determine intent and outcome it can be expected be incomprehensible.
