The 'extra pips' in particular does strike me as vague, because there are a number of ways that could be implemented that satisfy the wording given.
Again, not sure how it is vague. It is pretty clear that each additional crew member gets an extra pip that they can assign where ever they want in addition to the standard pips...
Every crewmember also has access to a power distributor pip that they can assign dynamically. This is in addition to the standard pips that the helm controls. This extra power distribution allows the ship to operate more effectively, increasing its capabilities in combat.
What are these other "number of ways" this could be implemented that satisfies the wording?
