In the other thread I posted about a large drop in CTR on Tuesday which was unexplainable however yesterday's CTR was on the higher side. So its either one or two things at the moment:
1) The daily adsense reporting is not getting an appropriate amount of server resources resulting in delay's, click dumps and even things like CTR updating at different times from the rest of the numbers which is making it hard to read until the next day.
2) Google are actively testing different algorithms which are producing strange numbers some good some bad. Traffic being roughly the same this week (discounting bank holiday Monday) I saw a very poor Tuesday with terrible CTR and CPC on Wednesday it improved and Thursday it's now a fair bit higher than the new average. It's usually Monday is my highest going down a little each day to the weekend. That's why im finding this week really strange.
Talk about a roller-coaster but I do hope this is Google's attempt to strike a better balance between interest based adverts and the normal targeted adverts.
