Can I ask why you capped your sync at 54 ?
To get DLM to remove interleaving and delay

to get as little errors as poss on the ds so dlm would relent. It was only a temporary cap until I went back to fastpath (I lost fastpath for an unknown spell of errors) at which point powering the modem off/on cleared the cap..
now back to 71 on the ds and it's bee  fine since.

The OP is already capping at 60Mb to try and get DLM to relent.   
I think he meant is there any particular reason why you capped at 54Mbps..  ie why you chose 54Mbps to cap at.

I'm interested too. Is 55mbps a magical threshold?  Not trying to be funny -- it's a well-advertised BT retail "upto" quantity.  Was it just plucked out of the air?

Ahuh...  that's how I read the question he was asking.     

Jmacp said in his first post "I have manually throttled the connection to 60mb / 20mb to hopefully get speeds up." so he obviously already knows about the use of temporary capping to try get DLM to take action quicker.

Hi

Let me clarify I was asking why 55mb is there a reason ?  Or do you just choose as fast a speed as you think your line will be good at ?

Thanks

The lower the cap, the less ES/FEC the line will have.
There's no specific number to set a cap at.

To shake my interleaving (which had been on the line for 9 months despite being ILQ green for all that time) I had to get my ES down you under 20 per 24 hours.

Your ES are in the single digits so I think your cap is sufficient. Give it 10-11 days from applying the cap to see if interleaving drops.
