No need, I bumped to 330 a long time ago and it's been synced at just over 300mbit ever since.

Still annoys me they are allowed to sell you an "up to" speed which you will never ever be able to reach, but such is life.

Tbh this thread could be closed if I knew how.

That's good as you are much closer to the cabinet.

My throughput speed are 151/29 on ethernet (I hate up to speed) The engineer agree with me if my line max was 210 why not go for 210 instead of 160. He say it down to openreach product 160/30 and 330/50 and you get less on overheads and ip profile on both.

Nothing special about this on G.Fast. It has always been the case on all Openreach xDSL products. Even non-BT Wholesale, though they are the one with the widely known-about IP Profile.

What might be different is the advertised speed. On ADSLx and FTTC, as you know, they have to advertise "up to actual highest" for the product. Not "up to sync speed". They should be doing the same on G.Fast, I haven't checked.

FTTP is different. It always connects at the advertised speed. (Pedant mode - Or not at all). What happens about throughput I haven't looked into.

Would coming from FTTC to G.Fast would reset to a 10 day training period

No, I thought that as well. But someone told me from kitz forum that FTTC and Gfast don't have 10 day training period. Only for ADSL/ADSL2/ADSL2+

Even on ADSLx the 10-day training was a myth promulgated by BT Wholesale. Their DLM always trained from Day 1, and the tenth day was merely the point at which they set in stone the lowest sync recorded in the period as the MSR. (Maximum Stable Rate).

From the MSR they set the FTR (Fault Threshold Rate). 70% or 80% of MSR, I think it started as one then changed to the other.

If you subsequently had a sync above the FTR they would not generally accept fault reports about low sync.

BTW still maintains this myth on FTTC . ISPs using their circuits have no option but to parrot it. On LLU and non BT Wholesale FTTC it can't exist, precisely because they don't use BTW. The relevant DLM on LLU is whatever the ISP may or may not provide, and on FTTC it is Openreach.
