I overheard ahzi talk about the ramps on octagon so I decided to see what was going on. There are 3 different elevations.
Starting from the center of the 'octagon' and moving outward you have the lowest elevation until you walk up a few steps. The end of the "low" elevation is shown by the red lines. Then there is a narrow strip of "medium" elevation in between the red and black lines. Then there is a slightly bigger strip of "high" elevation which is only the area inside the black lines. As you walk down the steps you once again have medium elevation.
The top 2 ramps (NE & NW) operate how you would assume with the gray area actually being the high ground, but for the bottom 2 ramps (SE & SW) the high ground is actually in the middle/top of the stairs. While the lines might look carelessly drawn I put in effort to make them as accurate as I could, especially the bottom ramps. The borders just look like that. The top ramps may not be quite as accurate because I got frustrated since the elevation borders didn't follow straight lines as cleanly as the bottom ramps and I had already spent a lot of time on this.
doh, I didn't know scm draft showed that lol. My hand drawn lines ended up being pretty close eh. That link only shows the high ground though, does scmdraft also show the low and mid ground? The mid ground still gets high ground advantage to the low ground.
it's kinda weird because of the blend of temple stairs into high temple terrain
on the pic the height levels are shown, the unmarked area is low ground, in blue its middle ground and high ground is red
so there's miss chance along the red arrows, which works as intended
however there is also miss chance on top of the ridge (yellow arrow)
there is no miss chance where the green arrow is
also top side ramps work different compared to bottom side ramps. on top side the high ground area is mostly made of grey temple tiles, but on the bottom side the high ground is made mostly of stair tiles
I guess that confirms what I worked out manually. I'm surprised my areas were so accurate for just firing units at each on the ramps. Your green arrow is firing on the same elevation so I wouldn't think people would expect a miss chance, it's just that they don't realize it's the same medium elevation.
Practically you only have to know where the high ground is and that you never want to be in the middle of the octagon fighting away from the octagon, that you at least want to be up a few stairs. When you're on the low ground you're missing shots no matter where they are on the ramp.
After looking closer at the images and confirming them in game, the shaded areas in scm draft are a little bit inaccurate. For example, the middle-ground borders of the bottom left actually look like this and are closer to my initial drawing.

the shaded areas accurate. there's no way for them to be "inaccurate"
rather, the geometry and how the conditions for miss chance work is not what one might expect without looking into details
I don't know why or how, but the shaded borders aren't accurate. I just made a video that demonstrates it on the southwest ramp. According to SCMdraft all 3 ghosts should be on middle ground, but only the center ghost is really on middle ground. The left ghost is on high ground and the right ghost is still on low ground. I eventually move the left ghost around so you can see that little 'triangle' of middle ground shown in SCMdraft doesn't exist. That border is parallel to the stairs.
I put X's where I have the ghost placed on the following picture:
