Alex estimates a larger saving, roughly 40 percent, without presenting a calculation.

Asked whether the saving might be 10-15 percent, Alex suggests more than 15 percent and offers roughly 40 percent. He gives no baseline fleet, price model or detailed calculation in this short reply. The number is an approximate estimate within the continuous-production discussion.
