There's C++ code included – great! But no actual timings :(

I'd be curious to see a deeper discussion of practical run-times, in actual seconds, relative to other popular sorting algorithms. Especially if driven by a real task with well-motivated problem constraints. (As opposed to "1000 random integers!" micro-benchmarks, or "N goes to infinity" theoretical big-Ohs.)

I personally find practical benchmarks the most exciting. They also help me identify different niches for different algos (caching, locality, array sizes, parallelization…).
