Watch Mersenneary's videos, particularly the classroom video.Generally it's just going to come down to "shove wider if he calls tighter, shove tighter if he calls wider" at 8bb or less and the differences are very thin.  I wouldn't spend time memorizing charts or anything like that, your time would be much better spent memorizing or making charts for 3bet shoves/3bet calling ranges as well as studying postflop spots (particularly OOP, if you're not calling a minraise OOP or not raising limpers much at 20bb or less you should definitely take a look at some theory/studying in those areas).The charts you link to as well as some other in depth posts (spamzor's end game thread, the many topics about this on 2p2 as well as a few on husng.com here) are all well and good, but it gets to be a bit of overkill down the line if you spend too much time on this.  It's almost like making preflop charts versus various player types 50-75bb deep on your button.  Generally raise a super wide button range unless you're playing an incredibly loose opponent that is also aggressive, in which case you can tighten up some.  But it's something with a little bit of work, well pointed logic and focus in game that you should come close to playing maximally best 8bb or less shove or fold and 75bb button raising ranges.But I'd just suggest primarily working on 8bb or less via watching Mersenneary's videos.  The spots will come up naturally, be correctly analyzed and interpreted with the best decision being made and portrayed to the viewer, but you'll also learn a lot about the more difficult to measure spots and really the more valuable spots (where opponents make larger mistakes on avg and your decisions are much harder) such as 3bet type hands and postflop play in the end game.

Yeah, I absolutely recommend you Mersenneary's videos - he does a fantastic job explaining all these end-game concepts.One of the biggest mistake I made earlier this year was auto-piloting in the end-game and "blindly" playing Nash as deep as 18-20 bb deep, which just went horribly wrong.  There's so much more you can do with creative end-game play and it'll not only increase your winrate, but also significantly decrease your variance since you'll more often get it in with the best hand rather than having a super close coinflip-type situation.
