1) Form a fleet
2) Order the fleet to move to another sector
3) Watch as the fleet moves at a BREATHTAKING 2 m/s to their target.
Tested with not only full ships but also cores with just a power regen block and a thruster.
edit: I tested again using a cheap shuttlepod I use and they moved much faster. However, it was clear that they were not utilizing the full extent of their thrust. I have attached the ships for the sake of testing.
