3.39%, Table ). Regarding the PWC model, we noticed a large increase in 𝜀 , when we changed log 𝝉 for 𝑁 = 𝑀 (from 10.16% to 17.81%, Table ). Otherwise, we did not observe any change in either 𝜀 , or 𝜀̅ , . As for the hook model, only the second scenario led to an increase in 𝜀̅ , for all 𝑁 (Table ).
