Also for an increased continuity version it may not be a bad idea to trim off a little bit of the outside of the ridge part, sometimes when you want to blend something smoothly to another surface it can be better if the 2 sides don't try to come to the exact same shape because if one side just very slightly swoops upwards that upwards trajectory will get exaggerated in the blend. So it can sometimes be better to stop a shape while it is for sure going in one consistent direction before putting a blend on it. That's what trimming away some of the outside of the ridge part can help with.

Then to get a good blend you need to use "Add sync points" especially right before and after each corner, so the blend does not get twisted up as it tries to go around the corner. Also in this one I used Planar sections as well:
