The hotspots on my Mini D2S are slightly below the cutoff point, but I don't observe the rogue spot mentioned by the OP. Looking at the geometry of the parabolic reflector, shield, and the solenoid area, the bulb has to have quite a tilt for any parts around the solenoid to reflect rogue spots. That's what I hypothesized mattesonb has on both D2S units. (since the hotspots seem rather low for such a close distance wall picture)
