Yes, you are reading it right. Sorry, I forgot about the "special case" when the sync-time margin has been set to 3dB and G.INP is active. I have the same problem.
Normally the BT Wholesale IP Profile is set as I said. But in this case it isn't. On AAISP I can see my radius log, but unfortunately only for a few days back. What I see on a re-sync is that the connection speed reported by BT Wholesale to AAISP is considerably lower than the actual sync my modem/router reports. When on a 6dB margin they are identical.
My IP Profile is calculated as I said above (96.69% of sync) based on that lower figure.
Whether the figure is incorrectly passed from Openreach to BTW, or BTW reduce it for some reason before calculating the IP Profile, I have no idea. I gave up bothering AAISP about it, as despite a few emails between us they refuse to accept this is happening.
Though that exchange was a while ago. Maybe they have found it is common by now, but life's too short.
It's idiotic that OR lower the margin to give a higher sync, but it doesn't translate into a commensurate increase in IP Profile.
