I regret to inform you that the NYC subway has many more problems than you experienced. Before the pandemic I traveled between Brooklyn and Manhattan and problems were common. Much more common was just random slowdowns, sitting between stations, etc. that makes it a lot more difficult to know when you'll arrive at your destination.
I'm not sure, but it looks that OTP is much stricter measure than what I meant. I was talking about: I want to change from line A to B on station X (or exit on the station X)... Station X is closed, and I learn about that on station (X-1), or even just by not stopping on the station X.
It happened in Paris more than "extraordinary" number of times, so I have to put extra 15 mins to every important travel.
OTP sounds like: the train is scheduled at 3:25, it arrives at 3.26. Correct me if I'm wrong here. But if the normal margin is 5 mins for total time of travel, making it 15 mins is not nice.
