Battle value 4,136 of 4,294 exact. A shield is heavy and in the way: it takes a point of walking as well as the point of jumping already counted, and a large one stops the design jumping at all rather than merely slowing it. The test is the other half of this. Running and jumping feed the defensive movement factor and the offensive speed factor both, so a design whose movement is wrong is wrong twice over and neither rating says which. Checking it on its own puts 4,280 of 4,294 designs right and names the fourteen that are not - which is how the shields were found, five Black Knights running a point too fast with a medium shield each. It also pins the interaction worth pinning: triple-strength myomer adds its point of walking *before* MASC and a supercharger multiply, so the three compound rather than being taken in isolation.
