If the turbine is not developing significant power, the "average MGU-H recuperation" would be negative. There are only two alternatives. . . . Opening the waste-gate comes at the expense of a lower MGU-H recuperation: in fact, the average MGU-H recuperation (on straight) is roughly zero if the waste-gate is kept always open. . . .
1. The turbine still develops significant power with the wastegate open. or:
2. The quoted research paper is wrong.
