Phase shift is a time distortion and it varies with frequency. In this case the distortion is plus. As it's plotted, it peaks at high frequency resonance where the shift approaches 180°. The shift diminishes on either side of that peak and will eventually go to zero.
Ortofon used their MC200 as an example, saying that undamped it had spectacular imaging, but was unlistenable due to excessive brightness. Damping was required and imaging suffered the more damping was applied.
This analysis is looked on with some suspicion. It could be the rising amplitude response that caused the spectacular imaging or a combination of those two. Imaging is the only aspect of performance alluded to.
