Thanks Barry. Returning to the core topic of piping, do similar principles apply in human behaviour terms?
In NPS Committee meetings for instance, if you double the evident tension in the meetings does this result in a proportionate decrease the frequency of meetings? Similarly if you double the length of meetings does this have a similar effect on the frequency of those meetings?
