Please realize that Guido is talking about the nth degree of refinement taking 500-hours to shine through. If you'll look back at his early impressions of the Capri and my early impression of my Continuum 500 (which uses the Capri's pre-circuit) you'll see that we were both very favorably impressed very early on.
Yes, it does improve with more hours, but it's good after the first hour and very good at 100-hours, then amazing at 500+. At least that's the way I see it.
