Macbook Pro Retina loose backplate

Hello there,

I recently bought a new macbook pro retina 13 inch (late 2013) and i am really happy with the machine.

I used it for like 3 weeks without any issues, and really like the machine. However, i noticed, that when i slightly put pressure on the unibody (like bending it when holding with two hands, which you obviously wouldnt do in normal daily use) the backplate can move veeeery slightly. It really is just like a 1/10 of a milimeter or so, like nothing, but it kind of took away that super solid impression that i first had.

Since i have like no creaking or other issues i think my machine is just fine, but being a perfectionist this kind of bothers me a bit.

Did anyone experience something similar? It seems to me like the screws on the bottom might not be too tight, which causes this. Would it help to tighten them?
