I believe the APR thrust increase will be an increment above the derate, not to the full APR without the derate selected. If that is not the case, performance must be based on Vmcg and Vmca, if applicable, for the full thrust. In any case, those speeds must be calculated on the APR thrust.
In fact, the APR probably only add an increment above any reduced power set, if the throttles are left alone.
