I have had a huge jav addiction for the last couple years. Yes there are a lot of boring parts. My method is to open as many files as can fit on my screen at once and tile them. I have 4 screens on my desktop in my office, 2 of them at 4k and 2 at 1080. I get around 8 or more videos playing at once and whichever is most interesting at the moment I maximize on one screen and enable audio. The rest I keep monitoring and swap as my interest shifts. I also keep a spreadsheet open so I can take notes on the ones I view, I apply a rating and take notes on where the best moment(s) in the video are, the reason why I liked it, note the names of the performers, director and studio is and if it's real good I look for more from those people.
One thing that frustrates me with JAV sometimes is that the covers are always amazing, as they should be. But what's inside doesn't always live up to the hype - so over time I've grown to mistrust the covers a bit and try to review everything on my own, applying a rating of 1-10 to each one I view. Anything under 4.5 gets deleted but I am careful to watch it twice before I settle on that score, the way I skip around I often miss cool stuff the first time. (maybe the second time too)
I must have close to 7 TB of jav now on my NAS server. As a generous estimate I am possibly vaguely familiar with roughly half of it. I try to divide my time evenly between acquiring new stuff and reviewing stuff I have, but there's just so much of it and the hunt for more sometimes gets me so caught up I often neglect what I already have, but it's there for rainy day hard disk archeology.
I have to admit it's a bit of a sickness but it's also a very enjoyable one.
