Around 2.1/2 weeks ago I had a line rate of over 51Mbps with a sync rate of >50Mbps and actual download speed of 48-49Mbps.
On 11/04/16 after the first OR visit line rate dropped to 47.5Mbps with a sync of around 46.5Mbps and download speeds of around 45Mbps
On 21/04/16 line rate dropped to 41Mbps with a sync of around 40Mbps with download speeds of just over 38Mbps.
I managed to get my line rate back up to around 44Mbps by strategic rebooting and putting my old Mk2 filter back on in place of the Mk3, I tend to get better download speed with the mk2 but worse upload.
This morning I was synced at 44Mbps and after openreach I am now synced at 42Mbps with the mk2 filter but my line speed has now dropped to 41.7Mbps:

He also mentioned the earlier engineer, not sure if it was on the 11/04/16 or the 21/04/16 had done a lift and shift but all he did today was try a few different pairs and now I'm actually running slower than I was at 8am this morning.

are you sure he swapped pairs?

Well he was away for a couple of hours and told me he had swapped pairs and even though he could see the speed is now lower again after his intervention he just shrugged and said that's the best he could do.
I'm livid that no one from Openreach seems to want to try and trace the issue they have somehow caused for me in a methodical manner, they wouldn't last long in the oil and gas game with me  :no:

Ok that rules out the pair I think then.

To be honest your speed loss is well within expected loss of speed for crosstalk, that doesnt concern me, what does concern me is your frequency cutoff.

I could accept crosstalk if it had not been fine until openreach started fiddling. These where instant drops in speed after their visits.

Thanks for that. I'm just a bit confused by your terminology here.

To me your sync speed is 42102 Mbps
and your max attainable is 41752 Mbps

Yes that's how I see it, but the max attainable should be (and usually is) higher than the sync speed.

Yes, but the max attainable is just a number calculated by the modem as far as I know, it's not the line rate

Well regardless my sync rate is still far lower.

For comparison I've just found this from the 11/04/16 after my first openreach visit when my sync rate dropped from 49Mbps, I'll see if I can find one that predates 11/04/16

Found one but not sure on exact date, just know it was before 11/04/16:

So I take it your sync speeds are now in the FTTC B (Impacted) estimate?

Did you rule out your own extension wiring? I mean do you have any? are you connected to the master socket?

What was the original problem with the upload on the line? And what does the Openreach DSLchecker say for it?

Extension wiring is not the problem unless it has suddenly changed on all three days Openreach visited in the last 3 weeks. That and I have the choice of Openreach Mk1, Mk2 and Mk3 filtered faceplates, currently the Mk2 gives me the higher sync rate (above) but previous one where with the Mk3 which seems to drop the sync rate by 2Mbps downstream but increases the upstream slightly.

Yes connected to the master socket using a 0.5m high quality DSL cable.

As said above the original issue was upload of just over 5Mbps when the Low for FTTC A is 7.5 for my line.

Is the extension wiring connected to the master socket faceplate? It should be.
