why virtual waves help

Eh, the gaps in time between bullet waves are kind of huge really. "15x larger data set" would be an overstatement due to the redundant data of strongly correlated data points, but I'd still characterise it as a larger data set by some magnitude, due to how large the large gaps between bullet waves are.

yeah, but the bigger gaps also mean that there is less reason to assume that is how they really move... I supose the reason for using virtual waves would be something like:

There are several things that affect their movement profile (which are the things I want to segment on) If virtuality affects their movement profile, I should segment on it. If it doesn't I should use virtual waves!

But I am wondering whether one could in theory make a random movement that is simpler than wavesurfing and would not be any easier to hit than it would be with a gun that only uses firing waves. As I see it, the assumption behind virtual waves is that if I fired now, they would move in the same way that they are moving for the 2 or 3 incoming bullets. I am wondering if that assumption is neccessarily correct (with a certain margin of error) for any reasonable random movement. (I think there really could be random movements more complicated than wave surfing, in fact I was planning one, but when I realized that wavesurfing was simpler I gave up)
