Enclosed VC3.1 300mm Belt Tensioning

I've been trying to make sense of the belt tension and resonance graphs for an enclosed VC3.1 300mm I just made. It has the FMMM, Motor Decouple-Damper, an EBB42 and it's sitting on the floor (on floor tiles, so maybe that could contribute to my problems, though it does not have any noticeable rocking). I've watched the youtube video that is recommended everywhere for how to read and analyze input shaper graphs...how to read and analyze input shaper graphs..., and took a look at a fair amount of posts/messages here, but in trying to follow guidelines and recommendations from various posts, I'm still at a loss of how to tension my belts. I can't tell if they are over-tensioned, under-tensioned, or if something else is causing what I believe may be a non-ideal belt tension graph. The only thing I understand is that they should both have the same tension...which I can't really tell that either...maybe the upper one might need to be tightened a little more to match.
