Are you sure? I've seen cases where levels would seem to enable or disable the instructions. Let me give you a concrete case:
Coming from SE to N was always giving me the "turn right" instruction. For months I've had fights with it, the segment types, the qw, the locks, the steep angle, nothing worked. Until for whatever reason I got the two highlighted segments with the same level. No idea if having both the same was the solution, or if having the right one different from the left one, but clearly before it was everything 0 except the one coming from the south which was at 1. Is it a coincidence? Probably, but I won't touch it again.
Then I have several cases where in a freeway there's like a Y, one or more lanes to the left and the remaining to the right and I want to ensure the "keep left" or "keep right" is said. If the right lane is a ramp and the left is a freeway, I only get the keep right (or turn or continue depending on the angles), but never the keep left, even if there is a very wide Y angle. Except in one case I can't remember where, but where levels are completely messed up. And then I have the opposite cases where I ensure the Y is the same segment type and should just work, but there are also cases (I can't remember at 1:35am) where it doesn't, but again in a freeway with bridges and tunnels the levels are all different. So after the next update I do want to double check these "split lane" cases and compare the live result with the angles, types and levels, and see if there is anything to it.
If not, then I go back to the place where stuff happens (or doesn't) and I have no idea why.
I'd really love to have a route simulator on the editor, enough to simulate a single instruction. One would pick two segments, click on a button and see what instruction will happen when going live. Also important to allow to pick two segments of a roundabout and check the nth exit or ahead/left/right.
I have other segments where every month I try to adjust the angle just a little bit and every month I get the wrong instruction. Right next to that one, there's a case of a Y, where ideally would give me a turn left or a keep right. The turn left is easy. The other one was a turn right last time, so I opened the angle as little as I could, and now I get nothing, so for this update I closed the angle again as little as possible and will wait to see what happens.
