The next thing to start to check is demogaphics and traffic sources. Mobile devices generally show quite a few less ads, as well as viewers from remote countries.
This is why nobody believes yout 70-75% monetized prior. Mobile views are the bane of the YouTube earner and are hardly ever low enough to let people hit that high of a percentage.
Lolz this is a fact, for example 1st of july:
monetized views : 31000
total views : 39000
Believe me or not, It won't change these stats.
