Equation #15 · Chapter 6

Reversibility Ratio R_r

R_r = \frac{Impact_{blast}}{Speed_{rollback}}

R_r · Ch 6

Blast radius ÷ rollback speed. Build the Kill Switch before the feature.

Blast radius (impact if it breaks)20

Rollback speed (higher = faster)40

Result0.50

Ship it. Hand the CIO the kill switch and say 'press it.'
