Another issue that I have with warp drive in Nu Trek is how they don't seem to have multiple warp speeds.
Was it traveller, or some other game that had a VOID drive.
I think temporal tampering allowed tech to avoid warp factors. Destination is important, and energy input saves time, but it might be between hyperspace in Star Wars and what we see in Babylon 5--although that is rather like the Vaduaar "underspace"
Therer was a wing Commander manual that had an interesting blurb.
Here is my theory. Warp behaves normally in free space. Space lanes have cosmic strings along either side witha modified speed of warp.
Here in nu Trek I am going to say that warp travel (and here is the Paris striaght line thing again) is most effiecnt if a ship is in a straight line between not worlds as per normal--but between their host stars.
In this way, the gravity well of the two stars dead ahead and in front allow a tunneling effect. A ship knocked out of this snaps to whatever destination is closest--explaining what we saw in STiD even though they weren't done cruising.
It's harder on the ship, but allowed a quicker story exposition.
At least that is what I am sticking to.
