The current extension spring mathematical model expresses limits on Initial_Tension as constraints on stress at the initial point (Stress_Initial MIN and Stress_Initial MAX). This approach tracks the development in the A.S handbook. While Initial_Tension is an independent variable, Stress_Initial is a dependent variable and the Stress_Initial MIN and Stress_Initial MAX are of the FDCL variety.
It seems more intuitive to have these limits appear directly on Initial_Tension. This issue provides a branch to support the code changes necessary to reformulate the extension spring math model to make that improvement.
