I think you did roughly the same rough maths that I did a few months ago and arrived at roughly the same conclusion.
My general rule is that five-tile trains get two minutes to load and unload at a station and three-tile trains get one minute. Those are the only sizes of passenger trains I use, goods trains are seven tiles long.
However, once the national timetable starts to get populated, I might need to programme in longer stops in order to avoid congestion further down the line. But that's fine, I'll worry about that when the time comes.
