I believe so. If you login to MDWS and look at the all users chart sorted by INP - yours is the highest bar 1 non-UK user.
Have you considered the fact that by doing multiple re-syncs etc, you could fool DLM into thinking your line is much worse than it really is - in which case it may decide you're not eligible for the proper '3db' profile when that comes out and/or takes other action to 'fix' your line.
Edit: I think it's also 'risky' in that I believe your line is one of the few ECI ones which hasn't yet had g.inp removed. Personally, I wouldn't be giving DLM a reason to intervene..
