Movement Chart Speed 18

[PvK]

That's not the speed 18 chart - it's the speed 13+5 chart.

As douglas wrote, Emergency Propulsion gets a ship moving at speed 30 for the first days, and thereafter using up its movement points 1/day until it gets back on the usual schedule for its speed. Kinda weird, but makes a little sense for emergency propulsion. What happens, I wonder, if you exceed speed 30 through modding...

>30 means one move every day, and you waste the excess movement points.
