For Jungle clears, how often should I aim for a ~3:30 full clear, or is the meta to just 3 camp then gank, and forget about full clearing? 
This one guy I'm watching clears red side, then backs / ganks bot, then backs. 
There's one clear where the guy is done at 3:02, but he's taking completely different roons (Absolute Focus + 2 Adapative) than I am for it, so it's not doable. 
I swear it takes me at least 10 minutes to get my first clear done.
