I also am currently with Rpm/SB for two weeks now, and my monetized views dropped for 65% with Adsense to nearly 10% after partnership. It kinda scared the sh$t out of me to think I had to split 10% of what I was earning previously. Things are starting to slowly increase, but not near as fast as I'd like. Adsense also had real time updates for views, ad clicks, and so on. Now I'm stuck with a laggy Dashboard that is 3 days behind. I've gone days on YT that show no views then 3 days worth of views all bunched together.
And to add to a previous post. The new Apple firmware doesn't include YouTube (the version that doesn't display ads) the version from the AppStore does display ads. Monetized mobile views should be up by 65%. Considering my channel is all about modding apple devices, and 60% of my views are mobile. Thank goodness for that change!
