Really, the primary issues people have here (other than how highly you seem to think of yourself) is that you effectively cheated/broke the rules in your own challenge (while still making a big deal out of having done the challenge), complained about things you didn't test/look into beforehand and then made "corrections" for, and completely missed the point of pretty much everything that's been said.
I don't care what the challenge you're doing is, how hard it is or how long it takes to do, if you break any of the challenge rules then the challenge is forfeit. Emulator frameskip/turbo/whatever is generally accepted for challenge runs (outside of things like speedruns, where it goes against and would only hurt the challenge anyway), and I can also see adding QoL mods/codes that don't directly affect the challenge itself, but anything that breaks the rules or gives you a direct advantage is a big nope. You've already admitted to cheating, with your excuses for doing so primarily consisting of "I should have free levels here because I got them in vanilla." instead of actually learning how to do the challenge properly inside of BNW's environment.
As far as the whole "not having done a normal run first" issue, I can see doing a challenge run as your first playthrough if you actually test out each segment and mechanic separately and then reloading the challenge save after to actually do it. In basically every challenge run I've ever done I needed to go through certain battles/areas multiple times as well as test out several combinations of gear/mechanics to make it through certain parts, and some challenges basically require knowing the game inside and out to properly plan out and successfully run. For example, the SP cap you keep bitching about is something you could have very easily found if you spent time testing it rather than expecting it to work in whatever way you had in your mind. If you can't be bothered to take time to do this, then you really can't complain when something unexpected happens.
Even if you never did a normal BNW run, you could see how much experience you get from specific things by spending short bursts outside of the challenge (using the same save, just reloading later after testing) and plan things out rather than getting mad that you aren't getting the same levels you did in vanilla. BNW is not vanilla, and there is no reason to expect or require the same things that the vanilla version of the challenge should have. If I do a LLG of vanilla, I shouldn't expect the same levels doing one in BNW, especially since there's an option to turn experience off (not counting the level (re-)averaging and enemy experience differences).
Basically, all I'm seeing from your entire initial post and continued arguments is that you expected the challenge to go exactly like vanilla with the primary planning/leveling and didn't know what to do when things were completely different. So, you improvised by trying to make it match vanilla and then complained every time something new and unexpected appeared, as well as finding any little thing we say to make an argument about just to continue bitching. Since a NRB run of BNW is obviously not for you, how about playing it normally instead, or even doing an LLG? At least then you wouldn't need to worry about levels or EL.
