Nothing much to say really other than that I already said... The person concerned hasn't uploaded much and isn't online currently (cwave) but when he first came on MDWS he had no G.INP but a while later over two single one minute uploads uploads on the 28th Jan (and nothing since), the flag showing G.INP as enabled was set in the DSLStats upload and there was data in the corresponding G.INP data columns plus a high INP level. Whether has has the TV service I have no idea, it was something postulated on here some time back but no idea when.
His Bits/Tone are not very good for elucidating with certainly what cab he has BUT he uploaded a DSLStats result early on and that says:

So ECI it is. And on that date (2nd Jan) there was no G.INP but by the 28th there was for the whole 2 minutes of upload he managed.
Maybe it was accidentally enabled - or a trial - or a glitch - or even aliens, you'll have to decide or investigate further yourself.
