No, what I'm saying is:
- Currently, we can only have one ship be tugged by one tug. So make it that one ship can be tugged by one fleet of tugs. Then, add up the EP and Mass of the tug fleet, and plug it into the existing formula for the one tug per ship model. I see no reason to have more than one ship per tug, but I see every reason to have a few tugs per ship.
