I am on 80/20 with retransmission high
If I change to 40/10 will I be stuck on retransmission high or will it go back to standard

It should perform a DLM reset somewhat. I did this twice when I was on Zen (80/20 to 40/10, then 40/10 to 80/20). Both times interleaving got removed. In your case I imagine your line will revert to traditional interleaving and later on get G.INP again. When FTTC packages on various ISP's become one month contracts some day then this will be a nice method to perform a DLM reset :P.

As Ixel says above.  Product change should trigger what I've started to call a system level DLM reset. 
'System level' resets remove previous INP/g.INP and revert to INP=3.  g.INP should follow shortly afterwards.
Whilst it may clear INP and re-tx... it doesn't always clear banded profiles.


* Whilst I have used the term system level reset (no idea what its really called), but it appears to work by clearing out all the ILQ caution counters so they go back to zero.
This is different to a full DLM reset performed by and Openreach engineer which currently resets the line as if it were brand new - including the up to 48hrs of being on Open profile.
