How close is reasonable for nether portals in the overworld if corresponding portals are placed at the correct converted coordinate in the nether?
It is my understanding that a portal will seek one in the opposite world up to 128 blocks away in all directions BUT (and here seems to be the crux of it) it should select the nearest one. My overworld base is on a group of small islands with main base on one, farming on one, cattle on another, sheep and pigs also on seperate islands. The six Islands are from 300 to 600 blocks apart in a near circle
I have already made a nether rail tunnel system at 120 block elevation connecting all my distant outposts which are 1-3K blocks away in the overworld, so I am thinking of adding portals on each island into this system to travel rapidly at night without fighting off the drowned as I row across. Should it work as the nether ends will be only 40 -70 blocks apart?
I've had portals that linked properly in the nether and overworld that were about 15 blocks apart in the nether. The key is to make sure both portals are active before going through the ones you just made.
Since the coordinates are divided by 8, portals closer than 8 blocks from each other in the Overworld are likely to point to the same coordinates which would make it hard to have them connect reliably to different portals in the Nether.
40-70 blocks apart is no problem as long as you make sure that each portal is the closest one to the converted coordinates of the portal you want it to connect to. And you'll have to build the portals in the Nether yourself since going through an Overworld portal closer than around 1024 blocks from the converted coordinates of an active portal in the Nether will send you there instead of creating a new portal.
A portal in the Nether has to have the X and Z coordinates within 16 blocks of the converted coordinates of a portal in the Overworld to send you there, so going in that direction the Y coordinates won't matter at all.
When going from the Overworld to the Nether you'll have to make sure that any height mismatch isn't great enough to make the wrong portal the closest 3D distance from the converted coordinates or it will send you to that one instead.
The 3D distance is the Square root of ((X1-X2)*(X1-X2) + (Y1-Y2)*(Y1-Y2) + (Z1-Z2)*(Z1-Z2))
Ie: square the distance East to West, add that to the square of the distance North to South and the square of the distance Up to Down and take the square root of the sum.

All of my portals in the overworld will be very near sea level (63) or up to a max of about 90, and all of them in the nether will be at my transit system level (120). It's going to be very unlikely that elevation will be a problem, unless I build a portal on my MOB farm which is at elevation 196. Been thinking of doing that to get out of climbing up everytime I need to unload the take.
After I built my first portal to the nether and mined from near it up to the level I use for a transit system, I always build the overworld portal and activate it but don't enter, and then build the corresponding one in the nether to make the first link from that end.

Just testing.
