Hi Burr, I think I understand now.

Well, remember the Blend adapts itself to the directions of the objects it is connecting.

The shape you have on the left there has a tangent direction pointing more sharply up in the vertical direction than the one on the other side, so the half of the blend that attaches to that side correspondingly also goes up more in the vertical direction.

What would help to alleviate that would be to have an adjustable bulge for each side with 2 sliders instead of just one global slider that bulges each side by the same amount. An option to adjust bulge independently for each side is one of the things that I do want to add to Blend.
