not halving the actual distance covered is a standard vector gaming conceit, as it cuts the math involved heavily

YOu're calculating vector in m/sec, not m/turn
Given 1000 sec turns
Vps = G * Time
Vpt = Vps * Time

Vps = 1000 * 10 m/s = 1e5 m/s
Vpt = 1e5 m/s * 1000 = 1e8 m/t = 1e5 km/s

there's your 10,000 km/turn/gee

Yes, Marc explicitly rounds G=10 m*s² and C=3e9 mps

Math check...

Vpt = VPS x TURNS.

So if the number of turns is 10, then it would be VPS x 10, which would in turn, be 1000*10 * 10 meters, or 1000 x 10 x 10 /1000 km
