You could have printed a quadrature pattern on the back for not much more complexity. Just one additional sensor per strip. Even that wouldn't be an absolute necessity since you know which direction the rotation is going. A single series of bars with one skipped or widened for home would suffice. Then you'd be able to compensate more readily for slippage and stretching.
