I get that but I don't see it as justification to scale it to the Star Saber in any way, the Star Saber even has a Matrix as just one piece of it anyways, but it's a very specifically multiversal artifact while most Matrices aren't and can't really do anything on that level. Even in the manga it took multiple Silver Matrixes in addition to Golden Power to create something capable of combining the different timelines together, and those were far stronger than the average Matrix is shown to be.
Matrices themselves behave very randomly see: Armada Matrix stopping a planetbuster but Optimus having to die to manage that. I don't think it's something that can be linearly applied because it has a kind of kryptonite affect on his bodies.
