Does the Logistics bonus for governors not do anything?
Currently something of an anachronism held over from VB6. It used to be more important when spaceports could stack. I suppose one option would be to multiply the cargo handling modifier by the planetary/sector bonuses if there was a suitable installation on the planet.
To be fair: most of the time, logistics bonuses (commanders, admins, or governors) don't provide much value. With careful stacking of bonuses I can cut a few days off of each end of a trip. But trips are usually 100+ days long anyway. Getting a 6% or less bump to throughput rate doesn't really move the needle on my economic growth.
And since a fleet of multiple ships loads at the rate of the slowest ship in the fleet, logistics bonuses on ship commanders matter almost not at all.
But managing logistics-related personnel is still fun for flavor.
It's fun to drop a logistics-expert governor on a fresh colony and imagine them tightly overseeing the unloading of the first wave or two of supply fleets as the colony gets boots on the ground, and then making way for a governor who has more ability to actually produce things.
Why not just make the planet/sector governor bonuses just additional multipliers on the formula? I'd say even regardless of the presence of suitable installations. It's really not something a min/maxer can abuse to much effect.
