Editing Ship Crew (section)

===Effects of Repair, Scrapping and Refit===
When a ship takes damage, it usually causes crew casualties. When a ship is repaired, those casualties are replaced (by academy crew if available). The grade points of the ship are adjusted to account for the grade of the replacement crew, weighted by the number of replacement compared to the total size of the full crew.

For example, assume a ship with 400 crewmen and grade points of 250 is involved in a battle and 80 of the crew are killed. When the ship is repaired, 80 crew replacements are added to the ship. If there are 80 academy crewmen available with 100 grade points, the grade of the crew changes to (320x250) + 80x100) / 400 or (80,000+800)/400 = 220. Therefore the grade of the crew drops to 220. If no academy crew were available, the grade would drop to 200.

When a ship is scrapped the crew is removed. If the crew have grade points higher than that of the academy crewmen, they are added to the academy crewmen pool. To simulate the experience of a veteran crew assisting the academy crewmen, the number of crewmen added is equal to the Crew x Grade Points / Grade Points of Academy Crew. 

For example, a crew of 600 with 350 grade points is removed from a scrapped ship and added to the Academy Crewmen Pool. This race has a racial training level of 1 so academy crew have 100 grade points. Therefore the number of crewmen added to the pool = (600*350)/100 = 2100. 

When a ship is refitted, its new crew complement may be higher than before. If so, the additional crew is added in the same way as crew being added to a repaired ship.
