I recon 2.5 overnight and 2.7/8 official. Then for part 2 maybe 2.7 overnight and 2.9 official. However I'm not sure about calling it 'Power' because secrets and lies had quite bad ratings and that changed its named to 'secrets and lies' and if look at BB 13 and 12 they had better ratings, and neither ch had different names. So maybe if BB 15 was called 'Big Brother 15: Live Launch' it would have better ratings.
