A bit over 1000 frames slower than skipping the crystal (1068 by my measurements). That's less of a loss than I expected.
I don't know how many frames it would save to drag around wormholes, but 1000 frames doesn't look to be a hard goal to achieve. Might want to look at a few routes and estimate whether it would save roughly 20 seconds or so.
All it needs is a little optimization and some extra enemies to manipulate. Note, however, that fuel is really, really tight. With all the walls I've been crashing into, I had to stop thrusting because one more frame meant I lose the pod. I should be glad for that canister I shot.
