Richard, the intent of a lighter rear trigger pull is not to make it lighter, the intent is to make the sear engagement identical to the front trigger. When equal engagement is achieved the rear trigger pulls up to a half pound less because of the increased distance from the axis to the finger pull. In addition to your theory of reasons to increase rear trigger pull, Dan @ MST shared a popular theory there, that since rear triggers have more leverage, pull weight is increased so that it feels like the front trigger. To me this theory is BS and furthermore increasing trigger pulls also increases sear wear.
