All information represented is approximate- actual tangents required are based on many different requirements, such as:

Bend configuration
Actual radii required
Material thickness
Actual machine we are bending on (many machines can bend the same materials)
Complexity of bending (i.e. Spiral bent)
Distortion requirements (i.e. AESS)
