Default Pushrod Geometry

Hopefully I can get an answer once and for all on pushrod setup. After searching for hours on the Internet I still haven't come up with a black and white answer.

Even though i and Windows Paint don't get along very well I muddeled up a couple drawings tohelp with my question.

In this example, the dual servos are in the fuse and the pushrods are crossing each other. The pushrod angle in the drawing is a little severe just to help get my question across.

Most of what I've read says that for the elevator to have the same amount of travel the servo arm should be parallel with the elevator hinge line

It seems to me that to have the same amount of travel up and down that the servo arm should be 90 degrees to the pushrod.

Which diagram is correct for the same amount of travel both up and down.
