Well yea but the area of a triangle an be infinite like any other geometric shape. Haha. If you think of rise and run equation and torque then the greater the run the greater the torque. Like @hoshin1600 said, this isn't always true in application. There are too many variables. It may simply be that the 45° stance works better for you build. As long as it works. I would recommend trying other stances just for the sake of proof.
