Each of these analyses the difference in the departures of the 31 at each of the stops on Tuesday April 1st between 11am and 4pm. The correlation is the correlation between the headway and the time of day as we can see there is not much of a correlation suggesting that headway does not increase or decrease over time during that period.

The times are all in seconds, so we are aiming for a headway of 600 seconds. A maximum of 900 as that represents 15 minutes.

Slightly worrying is the number of departures for Lasswade Road being one fewer than Park Road and two fewer than Cameron Toll. We expect slight discrepancies at either end, a bus departing too early to count for Cameron Toll or too late to count for Lasswade Road. I will look into this and check which journeys have been recorded at each stop.
