I hav some doubts in cpm calculation.

1.if i upload 5 videos a day suppose both my 5 videos got 1000 view so my total view of all 5 videos is 5000,now how they calculate cpm?whether they take 1000 view of each video as single 1000 view or separate 1000 view.

if i upload 5 videos a day suppose both my 5 videos got 200 view so my total view of all 5 videos is 1000,now how they calculate cpm?whether they take 200 view of each video as single 1000 view or separate 200 view.

so if i get 1000 views each from 5 video then they take it as 5k view and calculate cpm for 5k view right
