A good example of this in practice is probably, but not necessarily, in University Avenue, Belfast. If you take the direct distance between a well used watering hole on one side of the street and the chippy opposite and called it X. To find the travel distance/time one must multiply that by A + 1 - 24 to reflect  the time of day, B + 1 - 12 to reflect the numers of sticky green drinks taken and C + 1 - 200 the traffic conditons at the time.
So at around 1am on a Sunday morning, with 14 of the said drinks taken and in light traffic conditions one could, if leaning slightly forward and tie at 90 degrees, make it across the road, with legs flailing in all directions, in around half of the direct distance time.

Nearlythere. Fantastic work. Can you get it incorporated in the next revision? As a useful calculation it is sorely needed by many of us.

It's a difference +/- less than 200mm if I remember correctly so 1400mm or 1000mm on the button is outside this (or am i just suffering from alcohol deprivation??).

The distance is not really based on a risk assessment as has been suggested, and the difference between travel distance and direct distance is one of the most basic principles of means of escape, where it has been used for decades.

The limits are from lowest = 1200mm to highest = 1600mm measured from floor level to the middle of the operating element. Anything outside of this must be subject to a Variation.

Glad you're paying attention Buzz. It is of course Bradbury Place. I don't get out much any more.
