Math is not an opinion.
Though by your own writing it already seems clear that 2x2 is 24 for you. You are perfectly free to wallow in your own ignorance.
LWC are still busted in 5.1 along with HLOD generation and a bunch of other issues, including but not limited to rendering pipeline and nanite problems.
Just like before, you need rebasing to deal with anything that requires any kind of accuracy.
That’s unlikely to change, ever, really.
