The thought behind it according to Churchill (who I would say is an "expert") was that the leverage to pull the rear trigger compared to the front trigger makes it feel proportionately lighter. That is why he recommended the front trigger pull to be 1/2 the weight of the gun and the second trigger to be 25% heavier than the first. By making it 25% heavier the "feel" for both triggers would seem the same.
