At least you posted a response Dancc. That in itself is appreciated.
I disagree about +1 ratings being "too big" though. Sometimes they are as little as 200K, and occasionally just over a million. So what I will do is take a million off your figures and use that as the official overnight.
Don't forget the likes of DS and Broadcast provide a short daily summary of the main ratings of the night including the commercial TV figures excluding +1. You can always use my roundups in conjunction with those ones for any primetime BBC1/ITV comparisons.
