It's roughly 88% of sync, so even if there are steps they are very small and can be disregarded.

The highest possible profile on FTTC (38717) is over 96% of the highest possible sync (39999 or 40000)

Good point - I was thinking of the WBC version. Sorry.

Worryingly, (for me), I did a BT speed test yesterday and found my profile was 38715. I have only ever seen 38717 before.

I appear to be on the 17a profile now, as my estimated uplaod speed is 11.5Mbps, where it was 8.9 or something before. I wonder - is anyone seeing a 38717 on 17a, or may things now be slightly different?

Mine's now 38716 - first time I've seen that.

I've got 38710, but no idea what my sync is.

Mine is:

IP Profile for your line is -38714 Kbps

So, reports show 38717, 38716, 38715, 38714 ... looks as though they are 1k steps

On 8c profile I had full 38717, now on 17a and on 38716.

Sounds like I'm on 17a then, all good!

Or are you ?

If 38716 is a 17a profile and not 8c you could be but it is not a very good assumption to make as people are also reporting 38715 and 38714 so where would they be?

I was aware that my exchange was not scheduled for cabinet upgrades until January - and may well still be on 8c ...
