They need to understand new package as well. Maybe new package is designed to reduce sensitivity as old package quite volatile. As mid runner is splitted less than 0,5 sec, Tost urged the team to get more constant and stable result rather than outright speed. However i tend to agree with u that new package is more inefficient as the outboard section guide airflow downward to help seal the floor. But if they do it correctly, it will improve floor sealing and help diffuser effectiveness as well so yeah, it would offset each another and may help to better performance overall. Also next year as the outwash canard is prohibited, they need to discover new idea how to fight tire wake.
