Actually, you quoted me, not Fryon. I wasn't even addressing Fryon in that discussion, but Graeme Dice, who was saying that SE4 started out with faster-than-light drives (i.e., speed 6 would be greater than light).
This is an interesting academic question, but as long as there is no interstellar movement without instantaneous warp points, it's of course not practical at all, for gameplay reasons. SE4 maps and movement are hugely abstracted, and a ship that could move even 100 sectors per turn would er, change the gameplay quite a bit.
