Pre-loading of any sort I'll give you, but I consider fast learning one of the strengths of DC over VCS. As you get more data, it automatically tightens its bounds and uses more relevant data. To achieve the same with VCS you need to layer buffers of different complexities or dynamically segment.
Circular targeting or RetroGirl/Gun certainly outperform a DC gun with no data, and I am crazy enough to have such a gun just for that purpose... But from what I recall, it's like 2-5 data points (like 50 ticks into round 1) where my DC gun starts outperforming them.
