If that's not possible, do you have the separate Live + Same Day overnight data for the Sherlock episode just gone (how many watched it properly between 8.10-9.40pm)? Thanks.”
OK, so on Sunday, the Live ave audience for Sherlock was 6.845m, an additional 1.909m watched VOSDAL making an average overnight Live+VOSDAL audience of 8.754. It's 3min reach was11.578m.
Of those 11.578m, 2.173m watched (some) Wild at Heart on 9th January 2011, with an average of 1.725m watching across the programme as a whole. One thing I would point out is over that period of time it is slightly dangerous to run that kind of analysis, as the BARB panel churns around 20-25% of panellists a year. Now, the negative binomial distribution does try to correct for these imbalances caused but it is still probably a slight understimation.
