The Rook that jumps its first two squares might also derive a measurable advantage from ease of development and stealthy attacks, especially if Muller's computer tests are undervaluing the Rook due to early-game bias. Controlled testing on Chess pieces is very challenging, since they have so many interactions and emergent properties; devising two pieces that differ only in the property you want to test is difficult and fraught with error.
