djc8080; First, Welcome to WW and the AdSense Forum.
eCPM ranges from $0.10 to $1.00. Mean is probably $0.25
Those seem like kind of low numbers.
AI gets complex when millions of rules conflict. Adding CPM to CPC optimization can confuse even my fellow MIT alums working at Google.
Toss in a little CPA action for kicks.
