Cool project and very nicely done!! claps. You know what, I used to plan my leaving from home based on the timings at the station, but soon I realized that it is not worth it. It is not because trains are not sticking to the time table. Just randomly starting at your own comfort eliminates the anxiety that comes with planning. Your average wait time might increase to half of the interval between the trains, but that…
I would be interested to know how the service frequency affects this approach.
A nearby regional train line I sometimes use has a service every 30 minutes, and - for me at least - that (in)frequency makes it definitely worth timing your arrival at the station.
