I had proggie some time ago. Lots o'moving objects so it was awfully slow. It was quite obvious to me to get rid of sqrt in func's that dealed with distance-relativety (FindClosest ...). But still, when you need distance (not relative but precise), its greeks way or the highway.

Spread is good in terms of math, nice in optimize stage, probably. But there is no simple or obvious representation of it.

Overall, interesting... how da hell all that high-math would look after this...
