"Many casual listeners cannot even detect such a small change in tempo." Maybe not consciously, but their heart can probably (literaly) feel it and react differently, which is what this is mostly about. And in general I totally agree, that there is way more to music than tempo and I am only partially into anything techno as I like more instruments and variations, but with electronic dance music the rhythm simply matters the most for dancing.
