We estimate your download speed will be between 49Mbps and 50Mbps

Your stayfast guarantee hasn't changed, it's the speed you agreed when you entered the contract, the lower speed on a renewal is based on how your line has performed recently.
I'd advise reporting a fault, get the speed back to what it should before renewing, otherwise if you renew you're accepting a lower minimum guarantee, once the issue is resolved then renew, if it takes longer than 30 days from your reporting it for the speed to return, you can claim £20 (up to 4 claims per year)
in order for the forum members to help please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information .
Speeds often reduce over time normally due to more customers and crosstalk
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

Someone may then be able to offer help/assistance/suggestions to your problem
from what you have posted were you having problems with your connection dropping or maybe doing resets to try and improve speed or maybe both Looks like even though you have 6 days stable you are in a banded profile hence why stuck at 35mb. your upstream was 13mb on 18/7 but now down to 10mb
have you tried using the test socket with a filter to see if that improves your attainable as actual as banded will not change
Dslchecker suggests range 73/53mb
Had no noticeable problem with connection dropping and haven't done any resets but inadvertently switched off power to the modem which ties in with the six days or so stable situation.
Unfortunately the master socket is located behind a group of heavy cabinets which straddle the full width of our dining room which means a good number of hours to dismantle and reassemble. I hold my hands up , this is of my doing, the socket was fitted by BT in a suitable and accessible location in the dining room but subsequently I installed the cabinets without first having the socket moved.
I have an extension cord from the mast socket to the telephone and adjacent modem
That could easily be the reason your connection speed is not within the expected range shown on dslchecker
You may well be right.
However as mentioned in my initial post there were four (possibly I said three earlier) separate occasions where my download speed reached and exceeded 40Mbps.
These speeds lasted for about a week before slowly decreasing to 30-31 Mbps.
All the speeds quoted by BT and shown in dslchecker are connection speeds not download speeds there is no guarantee on download speed
The speed guarantee is sync speed as @imjolly states but also when connected to the master socket, not when connected to the master socket via an extention lead.
A big mistake not getting that socket moved before the units went in.
