 Proponents of  (G*1)  or  (S)  may retort by reminding us that this apparently problematic implication is the result of taking into account the relevant counterfactuals, and that not taking them into account is too costly. While Procrastinate’s ⟨agreeing to review the paper⟩ is part of the best act-set that she can perform over time, it is also part of the worst act-set that she can perform over time, and the worst act-set would be performed if Procrastinate were to ⟨agree to review the paper⟩ (Jackson &amp; Pargetter 1986: 237). Similarly, Jones’ ⟨going to the office⟩ is part of the best act-set that she can perform over time, but it is also part of the worst act-set that she can perform over time, and the worst act-set would be performed if Jones were to ⟨go to the office⟩.
