Ok well it hasn't been a week but I am confident enough to give an update
Firstly the router has been very stable without a single unscheduled drop. I tweaked the SNR to get me into the 2.5Mb IP profile which is a great result
SNR is virtually flat
~5ms better pings
Non existent bitswapping on downstream
RS corrected is just over 2%. High RS Uncorrected and/or RS Corrected errors is an indication of line issues. Can I be bothered to ring India ? Not if I value my sanity
It does not affect speedtest results adversely but I am pushing near the limit of what the line can handle
RS uncorrected and CRC are very low
By way of background:
"Reed Solomon is a forward error correction scheme (FEC) used on the dsl line coding.
On the physical level your dsl modem takes the bits from your PC and prior to transmission puts them in chunks called RS codewords. Each codeword also has some redundant bits attached to it. If due to noise on the line, the receiving modem cant make out part of the "codeword" it tries to use the redundant bits to re-create the codeword. If it is successful you get a corrected RS error.....If not successful you get an uncorrected RS error. From this you can see corrected RS errors do you no harm (but lets you know you are living on the edge) but uncorrected RS errors require retransmission of the data and makes you slow."
Routerstats I have made a lot of progress
For the router search text:
Use this URL for the stats page (or whatever ip address for the router)
http://192.168.1.254/status/adslstatus.html
Tick Use source A, get the page and mark the stats that you want
Telnet:
login set to admin and password - cannot see an option to use a different password ?
Change telnet prompt to >
Change chipset, command set to adsl info --stats
Most of the telnet stats and Bits/Tone work except for Up/down connection rate and max rate - displays just 1 or 2 figures
Update version 6.6e work fully now - tick alternative data format on the Telnet tab
This is one of the best IT purchases I have made and an outstanding router for a long/difficult line

,... RouterStats works on the 7700N the same as it is working for you.
