It seems the network of roads built in the 40s, 50s and 60s just can no longer be done efficiently.
Not uniformly. New York's LIRR (90 to 95% [1]) and Metro-North (99% [2]) feature on-time rates that rival the Swiss (93% [3]).

> A commuter train is considered on-time by the LIRR if it arrives within 5 minutes and 59 seconds of its scheduled arrival time.
The second source doesn't say, but let's assume it's the same as for LIRR, i.e. 6 minutes.
It's also unfortunate that the SBB doesn't immediately tell us the metric, but I happen to know it's 3 minutes (more specifically 2 minutes and 59 seconds).
In other words, the LIRR permits a delay of twice the time as SBB for it to constitute late. The S-trains in Copenhagen now has a punctuality of 97% using a 3 minute metric.[0]

Not sure how you compare a small simple system like Lord which is pretty much one line with a few branches with an integrated multi-national system like the entire Swiss railway either
As for the LIRR, it seems it's only the terminal station that counts:
> Thus, a train is considered late only if it arrives at its final destination six minutes or more after its scheduled arrival time.
And yes, in Germany this happens and is reflected in rising "cancelled train" statistics. KPIs for Deutsche Bahn managers haven't caught up yet ;)
