SNR 2.3 still holding on

I think it must just take an average of the snr's though.

All those 0's will average my snr lower? the lower frequencies are quite high snr but once you get higher they start to drop off to 10... So maybe the total snr isnt a good way of telling how stable a line would be? and I could be stable on a higher sync, just more high frequencies will be used but they will have low snr.
