It is a distal approximation delved from the African Hooded Raven...you know the big black birds that shade the water by spreading their wings over their head so they can better see the fish they hunt? The distal approximation part comes the length of wing span which exceeds the birds beak tip combined with total wing length from root to tip. Manufactureers used this proportion/ratio to determine where to stop the dampers based on the theory, as far as the birds are concerned, that anything past their beak...(or damper stop point) is interesting but essentially useless...therefore they might as well let it do what it wants to do and not waste time and energy fooling with it. Unfortunately there are several sub-species of these Ravens and each have a different beak-to-wingtip ratio.....obviously different manufacturers used different sub-species of Ravens and consequently we have as many different stop points for dampers as there were sub-species used. Although this, i.e Distal Raven formulae, is a rather well known fact in the circles of the intelligentsia of our craft I'm not quite sure just how the rabbits come into play............Hmmm.
