It is a sevice called Logic Dictates that makes "Beyer like" figures (same scale). Their figures for that day were almost identical to the Beyer figures. The guy that makes them told me he and Beyer had independently concluded that the variant for that day should be split staring with the Kings Bishop.

Not arguing that they are right and you are wrong (you in fact seem to have had a better grip on the day's figures). I am just using that day as an example of one of the problems I have encoutered over the years making figures myself and observing the work of others.

The pace sometimes impacts the time and figure makers sometimes adjust the variant for the race. That opens a can of worms for trip handicappers that might double count etc....
