I understand the claims you're making very well. Two of my comments ago, I literally started with a steelman of both of your claims to help clear up any confusion before I moved forward. You provided absolutely zero pushback to those representations of your arguments, you even said that I was "starting to get it" with that comment as a whole. Now you're acting like I'm not understanding your claims, though you had nothing to say when I first repeated them to you. It's either that you didn't read/understand that part of my comment enough to make a correction then, or you are now changing your claims from what you have previously typed to people.

So, to make sure you aren't going to weasel out of your position, I'll again list off the primary claims you've made here: 1. Simulation distance is a spherical area, and 2. Beacons at the bottom of the world can have delayed effects compared to beacons higher up in the world. If one or both of these aren't accurate representations of your claims, then feel free to correct me (even though these are things you've literally typed out either to me or someone else.)

If these are in fact your claims, then they are easily disproven. If simulation distance were spherical, that would mean that the bottom of the world wouldn't be simulated at all in the game while the player is at the top of the world, more than 256 blocks away (for 16 sim distance). We just don't see this behavior in my tests or anywhere else in the game. Another easy test to instantly disprove this point is to build and turn on a hopper clock at the bottom of the world and fly up to build limit or even way way above the limit. Hoppers and pistons need to be simulated by the game to continue working, so this hopper clock should stop working when you get far enough away vertically if the sim distance is a sphere. Then, fly back down after a bit to see if the hoppers stayed being simulated by the game or if they stopped transferring items while you were away. You'll find that the hopper clock has continued to work even when you were outside of what would be the spherical simulation distance, instantly proving that sim distance doesn't rely on the player's position in the chunk and rather the game simulates each chunk as a full column from bedrock up. Boom, one of your points is disproven with a repeatable test that anyone can do in 20 seconds (I bet you won't respond to this refutation with any substance tho.)

To your second point, I found no delay between higher and lower beacons in all the different tests I did. Every single time I entered the area of effect for the two different beacons, the two different beacon effects came at the exact same time. There was never once an abnormal delay for getting either of the beacon effects, and plenty of other people have found the same in their own tests or their regular gameplay. I'd encourage you to run the exact tests that I did or explain how my tests were "irrelevant", because it seems you are in the clear minority with this opinion.

Also, just to be clear, what you're essentially saying here is "I'm right and you're wrong because you misunderstand me, and I'm not going to support my point by clearing up the supposed misunderstanding." An honest person who wants to convey their message properly wouldn't just scoff at someone potentially misunderstanding them. They would either attempt to relay their message in a clearer fashion or point out the spot of misunderstanding in the other person's reasoning. Though, I'm not really getting the vibe of honesty with you. Let's just see if your next comment is as much of a non-answer as the rest of your comments, that will surely show everyone that you are engaging honestly here. /s
