PPLNS in general (shifts actually simplify it for reporting) is hard to explain in a table. If I were a graphics designer it would take me no time at all. I think the key to explaining PPLNS relies in either a real-time conversation, a LOT of images, or the best way: an animation.
A simple GIF could probably clear up PPLNS misunderstandings in under 15 seconds :/.
Yeah, I was just thinking it would be cool to have an animation of coins flying from the new block and landing on the 10 shifts.
