Looks good. No worries, but keep an eye on the upstream when the weather gets warm. You really want the levels to be in the 40s, though up to 53 is okay.
With 3(or more)-channel bonded upstream, 51dB is the max for 32QAM and 64QAM, 52dB for 16QAM. I'm guessing the Zoom says ATDMA for 32 and 64QAM, and TDMA for 16QAM.
