The optimum downstream range is +7 to -3. It'll work outside that range if the SNR is high. The DOCSIS spec says +15 to -15 but el cheapo kit rarely works at the extremes. For example my SH misbehaves above +7 dBmv on good SNR. Due to an area fault, it's currently struggling at between -4 and -11 dBmv across different channels with poor SNR.

So 2 dBmv is perfect. -2 dBmv is also perfect.
