Yes it would be useful if other people contributed. Actually I agree it's too small now. Which means the 2D effect is too small also since it's exactly the same size as that now. I don't know how to resize the 2D effect though.
I'll scale the effect back up maybe 25% or 30% (giving a length in m is meaningless as the size of the effect in m is determined by the size of the ship warping in).
There is likely to be a bit of overlapping going on with any particularly tall or wide ships like the Sharlin (tall). This occurs when the effects starts to shrink down. There's nothing I can do about it. In an ideal world warpin speed would be turned on in the tables so the ships clear the effect before it shrinks. But in my experience the warpin speed feature is unstable, and often ends up with ships arriving from hyperspace and heading off into infinity in a straight line. Unless that bug has been fixed now.
