Guitar players struggle to quickly determine correct capo placement when transposing chord shapes to different keys

Musicians frequently need to play songs in keys different from the original, but lack a clear mental model for calculating capo positions when using alternate chord shapes (like playing E-flat using G-shape fingerings). This creates friction during practice, performance preparation, and live playing situations where quick transposition is needed. Existing resources don't provide intuitive, step-by-step guidance for this specific transposition scenario.
