When I used to take Amtrak in the US routinely for a 6 hour ride I believe it was 0% punctual by a definition much much weaker than that. I don't believe it was literally ever delayed less than 30 minutes.

Also in the US airports you can't always rely on security being less than 30 minutes (barring TSA precheck), so the idea of missing a flight because the train was 10 minutes late is an absurd thought here.

I lived in Europe for the past couple years and as an American it really is shocking how drastic the understanding of public transit fundamentally is in the minds of the public at large.
