isn't the gist of all this that if CPM campaign advertisers do target your website - on pages where your eCPM for CPC is higher than their bid (i.e where the CPC ads perform well) their CPM ads will not be shown. However on pages where the eCPM for CPC is lower than the CPM bid then the CPM advertisers CPM ads would show. This is how I see it working - apologies if I've missed something obvious.
