Don't think anything about Robocode itself should lead to an inaccuracy. Could it be a normalization bug? When normalizing angles, an individual angle is equivalent no matter how it gets normalized, but if you're summing or averaging them it can screw things up. E.g., average of {2.9, 3.0, 3.1, -3.1, -3.0, -2.9} is 0, but you'd want the result to be something more like pi.
Normalization should be irrelevant because everything is already relative.
I might be on to something though. I'm wondering if the inaccuracy is coming from the original absoluteBearing being used to calculate LV and AV. Should it be updated with angular velocities?
You'd need to keep a list of the positions you were in and backtrace the enemy movement until the wave could originate at your location - a sort of backwards wave, as it were, otherwise you are getting the angular velocities from your current location, not from where you were when you wanted to fire. Also, are the indexes for the VCS calculated using the values from when you were firing, or when you are having the wave hit?
All segmentation is calculated when the wave is fired.
Why do you think I'm getting the angular velocities relative to EM's current location? I store the absoluteBearing from the tick in which the wave was fired, and both e.getVelocity() and e.getHeadingRadians() are absolute and shouldn't be relative to anything.
Thanks
Ah, OK, looking at the source I see that you've still kept the wave structure, I thought you had completely gotten rid of it and then each tick look back to see what wave would hit now over the last N ticks of bullet flight time and retro-actively construct the wave from the conditions as they were then. What you've done isn't quite that drastic =)
As for what is different, have you tried projecting the point back into the cartesian plane and printing it to see if it is the same as the actual enemy location? How about using both types of tracking at once and seeing if they are giving the same results at wave-hit time?

I'm not sure, I'd have to see source code to properly understand what's happening here. But it seems that they aren't being registered as 'hit' at the same time. Could it be that?
That's what I assume.
Here's the current developmental code with all the debug code (I realize that it's quite a bit larger than 730 bytes.):

}Thanks
Doing enemyHeading -= absoluteBearing in the test() method breaks things because many waves are evaluated each tick, but even after fixing that I'm seeing very different values for Point2D.distance(sourceX, sourceY, enemyX, enemyY) and enemyDistance, which is where I suspect the errors are creeping in. Of course, I can't see anything wrong with what you are doing :-/ Maybe a step-by-step printing/debugging with only one wave in the air would let you see how enemyDistance is deviating from the old value on a per-tick basis?
For some reason, enemyDistance is always 20-40 pixels less than the Point2D.distance() calculation.
OK, it seems that was just some bad debug code.
