No, because that's assuming vector changes don't affect the difficulty of tracing. Fast or not, a strait line is a strait line. I can track things in a strait line far easier than I could in a chaotic 3-d situation.
Even though it's not as fast as 300 times lightspeed, it's still somewhere near 300 times lightspeed.
Not at all. We don't know what makes difficulty in tracking. Lines are 100% predictable. Pure speed may have very little effect on trackability except at massive levels, while unpredictable and multi-vector speed may throw him off at far far lower speeds, because every time there's a change in direction he has to reevaluate their whole course.
