Apparently a racist
Think of it this way. A hose clamp is 1/2" wide. When you wrap it around a tube bend, only the exact center of the hose clamp is perpendicular to the tube. Both sides of the hose clamp are not perpendicular to the tube where they are positioned. On the inboard (tight) side of the bend, the side of the hose clamp is 1/4" from the center. But it's also 1/4" from the center on the outboard(wide) side. The outboard side has a larger radius. So a 1/4" step on the inboard side requires a larger step on the outboard side to keep the line perpendicular to the CLR.
The larger the CLR of the tube is, the less this will screw you up. Unfortunately, almost everything I'm dealing with is on a 2"CLR.
Here's a picture to show what I'm talking about with the hose clamp. Probably makes more sense than my jabbering. The red part is the hose clamp.
