Perfect method, definitely. That would imply allowing a cuber to calculate a "God's Algorithm" (or near-equivalent, with nice fingertrick) intuitively in the amount of time they're allowed to inspect the cube in competitions (=unrealistic, but this is a hypothetical situation ).
Doing that on a crappy cube (i.e. Storebought) or the excellent ones we already have available > Doing a normal or crappy method on the most amazing cube in imaginable existence.
