IMHO the correct way to manage the SNR threshold is do do it
adaptively, measure the error rate, if it is high say over 30% reduce
the sync rate, if it then drops below say 10% increase the sync rate.
Have you seen what 1% (let alone 10% or 30%) packet loss does for TCP
throughput?
I've not seen it - what does it do? I'm guessing it has a serious
throttling effect.
