Partitioning of the parameter space according to which strategy is favoured, in the Example 2 scenario. Grey represents the feasible region; dark grey - strategy B favoured, light grey - strategy A favoured, given a disease complexity of 2. Blue, red, green and black dotted lines mark equivalence of the two strategies given disease complexities of 1, 2, 4 and infinity respectively. The black dotted line also represents when the new assay of strategy B provides no new information.
