A3d1) The puzzle must rest on the mat, not on the timer part of the Stackmat.
I would like this regulation to be removed from the next update of the regulations. It has always been unclear to me why this was added in the first place, I cannot recall any clear arguments in favor of it. Whether it actually gives an advantage is arguable, but I don't think anyone can argue that it gives an unfair advantage. Every competitor has the option to place the puzzle on top of the timer, the same way every competitor can place the puzzle at the far edge of the mat. Thoughts?
