It has been shown in earlier works that the vertices of Platonic solids are good measurement choices for tests of EPR-Steering. Such measurements are regularly spaced, and measurement diversity is a good feature for making EPR-Steering inequalities easier to violate with entangled states. However, such measurements are provably suboptimal. By scrutinising not only the average results, but also the measurement statistics of cheating strategies in a Local Hidden State model, we outline a method for devising optimal strategies for EPR-Steering tests with no detection loophole.It has been shown in earlier works that the vertices of Platonic solids are good measurement choices for tests of EPR-Steering.
