Some of the plots would have been much more helpful if instead of absolute value in seconds, the y-axis were the multiplier w.r.t binary search (and eyeballing suggests a relatively constant multiplier). Obviously, this isn't changing the big-Oh complexity, but in the "real world", still nice to see a 2-4x speedup.
