A bit too mathematical for my taste. I learned my tuning theory by owning a harpsichord, and learning to tune it. A harpsichord is more sensitive to the "rounding errors" in equal tuning, owing to the richer overtones, so equal temperament does not sound quite as good a compromise as it does on a piano. And those historical temperaments are so much easier to tune by ear. Besides that is what the they used at the time of Bach, so historically correct for playing Baroque music.
