Splitters and signal levels

Recommended downstream power levels are -7 dbmv to +7 dbmv
Recommended upstream power levels are
35 dbmv to 49 dbmv
(Modem manufacturer, Arris, recommends 45 dbmv to 51 dbmv)
I have a necessary splitter that splits to my cable modem and to my tv.
Even after that split, my downstream power levels are peaking at 7+ dbmv and my upstream are below manufacturer recommendation.
I decided to see what the levels looked like after adding an additional splitter and it actually makes my levels more in the median of where I want them.

My question is: Should I leave it there, or do you think I'd be prone to problems?

Ps: these screemshots are my Arris SB8200, but I also have a Netgear Cm1000.
Same situation applies.

Thanks in advance!

Are you having issues? 

Either one looks decent. You don't have errors.

If you're loosing speeds/packets/or having drops, then I'd have the isp check the line but otherwise it looks fine.
