The more i look at the BB rating the better i think it is up against 2 of the biggest shows in the country.
Also, it is worth noting that this weeks (first 3 days, saturday-monday), ratings are up on last weeks first 3 days.
(last weeks in brackets)
Saturday- 2.1m (1.7m)
Sunday- 2.85m (2.5m)
Monday- 2.3m with huge competition and unusual slot (2.2m)
So if we look at the trail, Tues normally does better than Monday by around 200-400,000 and also with last night being up against the soaps and on in the 8pm slot, tonight we could see a 400,000+ increase on last night... so 2.7m for tonight? (which would beat the 2.4m that last Tues got, beating previous week rating again).
So if it wasnt for the 8pm slots this week, it looks like we would have comfortably beat the last 2 weeks rating averages... we could still beat it.
Week 1 average- 2.9m (official of 3.3m)
Week 2 average- 2.4m
Week 3 averaage- 2.4m
Week 4 average SO FAR- 2.3m-2.4m
Also i think D.M.N was right about the twitter % and guessing how well the show can do, he predicted 2.1-2.3m based on twitter and he was correct with 2.3m.
So we can always use Twitter to predict the ratings.
