Yes at this point in time and with all the question I have and all the attempts and the delay to get the update to test the possibilities, it has been easier and safer to just delete the whole roundabout and all the Y segments, connect the roads as aligned as possible, and redraw the roundabout. I always do that when they are perpendicular 4 street crosses, as that way I'll then get the "straight ahead/turn left/turn right" instructions instead of "take the 1st/2nd/3rd".
Now this roundabout is a good example of how one learns and tries different things over almost a year. As far as I've understood the sistem, waze does moves segments and nodes around based on the gps tracks. This means that roundabouts will move away from the center of the circle on the satellite, and in certain cases where GPS coverage is less good, will even become slightly oval or completely dead like the first link I sent. And when this happens, the dozens of nodes of the original roundabout becomes much less, like you can see on this one. It was created round, then after some time it was completely fupped up like this but not round, we moved the nodes back to the circle, and that was around the time I learned that roundabouts *SHALL* always be locked, so it stayed like this for some months now thanks to the lock.
As I don't want to redo every single roundabout until I'm sure the redoing is worth the trouble and won't get screwed again, I'm concentrating only on the ones with the wrong instructions, or the ones with the Y segments. This one is working correctly, gives me the right nth exit instructions, and is better to get the nth instructions than the ahead/left/right (the roundabout is not plane, the NE side is higher than the SW, hence the water pound in the middle), so I'm not touching it - besides having double checked the latest stuff I've been worried about, namely ensuring the whole roundabout is A-->B and all with the same level and, just in case, q-w all nodes again.
In other words, it's not not being round that screws the roundabouts, that one I know for sure. It's being unlocked, that I also know for sure. It's the screwed after this that I'm curious about.
And because the less nodes the less traffic to the client, I don't really mind having a nthagon, it still looks round on the client.
