Since I recently had my drop wire replaced and discovered it was damaged on the Plusnet pair, I figured the result might be interesting as that's my G.INP line.
Touch wood, so far the Home Hub 5A with OpenWRT has been so much more stable with the SNR tweaked.

If I'm really lucky, maybe it wont get banded like my Zen line did which disabled my SNR offset. Although so far, I'm not getting any real-world throughput improvement here, something is throttling it, its not even doing the Line Speed reported on the Plusnet portal which is 68.8Mbps.
