That's fine - non-quantitative (a.k.a. "gut") reasoning is a valid and useful cognitive tool (in certain contexts), in fact.

If I was to give a "gut" estimate for the overall deterioration of the subway service in recent years, though -- I'd peg it at closer to 30 or 40 percent than merely 20.

A NYC Subway that’s 40% worse than it was 10 years ago is still by far the best transit system in North America.

Now, look, that doesn’t mean it’s good that it’s declined so much, but context and perspective remain useful.

But compared to just about any major city in Europe... seriously, it's almost a joke.
