You seem to be getting into some spats, VMboy!

Anyway, like said, 10.6dBmv is not generally recognised as a problem free receive power level based on recorded experiences. In your first post you said that a couple of days ago things were normal after 10 pm. We don't know what your power levels were then.

The receive power level starts from the CMTS at a fixed number - a much higher level than your modem reports. Fibre, cable, junctions, splitters and so on all provide impedance (to keep it simple) and by the time it reaches you it should be a low value - ideally 0dBmv. There are tolerances for integrity depending on how your data is packed (the QAM value) and that physically stretches to +/- 10dBmv.

If your receive power level is always what you've reported, then there is stability in the impedances and the only problem you may ultimately face is a modem that objects to being hit with more than 10 dBmv.

I suppose if you're directly connected to an optical node at the regional hub rather than going through a cabinet, your receive power level could be higher than the normal user; in that case the engineer would fit a forward path attenuator to your modem because it doesn't need 10.6 dBmv to give you a stable service.

Maybe the above explanation rows back somewhat from my earlier "much too high" suggestion. But I think you should get it attenuated and on this occasion it may not be (yet) the cause of your poor experience.
