Yes.

Those are subjective criteria, to decide if a country not only "efficiently" settles a matter, but it also does so "quickly".

Similarly, there's not a single country where we'd find there is literally "no corruption", which means it's just a subjectively strong form of "nearly nonexistent", or where we'd find there is "no expropriation" ever in its history, as opposed to it just being "highly unlikely" to happen to you.

These subjective differences account for the difference between a 90/100 and 100/100. So if your example was that only 10% of the score depends on the difference between a figurative "no corruption" and "nearly nonexistent" corruption, you've done a very poor job convincing me it's an objective test.
