I reckon that the higher service frequencies also play a part in St Albans' favour, in that there are fewer consequences of missing a specific train, and you don't have to run your life quite so strictly according to the train times.
Perhaps ironically, walking might be the best way to arrive for a precisely timed train. The time taken to walk a given route is very consistent indeed, far more so than going by car if there are things like traffic lights and crossings to contend with. For a journey you do often there'll likely be just seconds of difference between the journey times each day.
