For example, in a 5 ship list, my 34 point Kenyan only has to do 20 percent of the work.
Keyan, adv sensors, stay on target
Rookie pilot x2
Bandit pilot x 2
In this setup, both the rookies and Keyan can underperform and still pull their weight, though it does place a burden on the bandits. Bandits being as efficient as they are, an extra 8% of work format seem hard to manage.
So why don't we take the whole list into account when we get into whether or not a ship is worth it's cost?
