Why 307

I had an Openreach WBC FTTP 330/50 connection installed at the beginning of November, during the last month I have performed many speeds tests both wired and wireless, but the fastest I have ever managed in off-peak times is 307 Mbps. My original estimate from BT Retail was 313 Mbps, so it's not like there is any issues, but I wonder why it's not the full 330 on a FTTP connection?

What factors (apart from network congestion) actually lead to a FTTP connection not running at full speed?

Out of interest, does the upstream always give a tad over 50 ?

Nope, it's pretty much 49 all the time

330 Mb/s will be the �sync� speed, after overheads you will get around 310 Mb/s. If you�re getting in excess of 300 Mb/s in Speedtests you�ve got nothing to worry about

Somewhat odd, all those I�ve tested get a shade over the upload.

I totally agree, just did a few tests as I do now and then and yes its about those speeds.

Speed tests were done while others here were using the internet like watching Twitch or YouTube etc.

Those speeds are at that speed 24 / 7

What was strange was when we were on Infinity 4 (300:30) we did see the odd faster speed, however the average speed was all over the place, where as with Ultrafast 2 Plus we get a stable max speed.

I'm not worried, just intrigued

I do, I get about 300 to 309Mbps downstream and around 52 to 53Mbps upstream.

I did try with Linksys router and that did go just over 50, but not with the BT Smarthub

Thanks
