Taking
notice of the ratings from day to day like that isn't really useful or a good indication of a trend.
Normally true but not when the fall is as big as this. Dropping 160k and 4 share points in 2 days is a very worrying sign and to pretend otherwise is wrong. That's a 20% fall! The fall so far (percentage wise) in just 2 days is already much bigger than Daybreak1 had across all of its debut week.
Yesterday was down 150k on the same day last year with Aled and Lorraine.
Usually, TV programmes will find new viewers, and some of their current viewers will begin to drift away. Therefore, the yearly ratings are the only indication of success. The ratings don't really indicate a trend - they do sometimes, but not often.
