Lol, bro, bro, seriously. It's. Not. Hard. At all. 5th Gen non-CGear RNG is by far the easiest RNG. Even easier than pokewalker RNG. Most of my 9 boxes of 5th Gen RNGs were done at work. On break. No computer. No timers. No RNG Reporter. Taking maybe like 5 minutes per RNG.
Trust me, you just need to try it. You'll see how easy it is.
[edit]
And most of my RNGs were done before we even had a working RNG reporter, so you've got it even easier than I had.
