Experience_added = EPTrainingScale * Academy_bonus * Points / (Sqrt(Hull_Crew) + 1) ...where Points = Supplies if Supplies ≤ 25 Points = 25 + Sqrt(8*(Supplies-25)) otherwise Academy_bonus = 100 for normal ships Academy_bonus = EPAcademyScale for Academy ships
(4.0i) Academy ships receive four times as much experience from training.
