I'd definitely call that KNN (or DC as we do on the wiki), you are just using a discrete kernel density estimation to find your peaks/troughs. Your algorithm would give identical results if, instead of smoothing into bins, your reversed the loops and checked each angle for a 'score', which is just discrete kernel density estimation through sampling. VCS refers to the way that the data is gathered in the first place, smoothing the data into segmented bins as it is collected.

DrussGT doesn't use bins until it's time to surf (like you), instead just keeping a list of the last 2*rollingDepth hits for that buffer, but I did the math so that it is functionally equivalent with rolloff and weights, and as such I still call it VCS.
