You are way above your handback threshold speed and only just short of maximum speed, nobody is going to do anything with those sort of figures.
It is more than 6mbps more like 13 mbps because the transmission high. I guess that 13mbps can be sold off as a standard connection to someone else more profit to BT. Just with the sync rate at 74 and then my ip profile being another 10% lower.
The drop in connection speed is only 6mb - max possible 80 and current speed 74mb
as already said with that speed well within range BT are not going to be interested
After 25 days of no drops or anything and my connection decides to decline further down
Something is not right but if it keeps on lowering and goes below 71 then BT will have to do something as my minimum guaranteed sync rate is 71. so it is getting very close. My point of sale was also quoted 77-80 for the downloads I am getting 56. So that estimate is way off.
in BT letters the use of the word 'download' is clarified in T&C and is actually your connection speed not your download/thoughput speed which is the 56mb you quote.
I agree though that the way BT refer to download speed can be taken as throughput hence why clarified in T&C as connection speed
If your connection speed is dropping there is clearly a line fault, until that is fixed there is no point in a DLM reset as it will just drop again afterwards. But until your speed drops below the guaranteed speed, BT won't be interested.
The handback speed is based on your connection speed not the speed at which you download so until your speed drops below handback then BT may not take any action
if your connection is stable then unusual for a reset and drop in connection speed
