+1 on what the other 2 posters said. Since the length of action differs significantly from one maker to another I think referencing the balance point as the distance from the front trigger makes much more sense than using the hinge pin as a reference as the trigger is what determines the position of the shooting hand.

Also, intended use & personal preference on how a gun should feel is the most important part.

That said, Michael McIntosh once wrote something like "the lighter the gun the more weight forward it should be" & that concept seems to work well for me.
