Addendum, this source: http://www.pilotfriend.com/training/flight_training/fxd_wing/hsi.htm Reckons 5 degrees per-dot for a VOR, 1.25 for a LOC (yay, the 4x factor is sane) and 'about a quarter of a degree per dot' for a GS indicator, so the 0.32 term is plausible. It does also mention some alternative dot mappings when the HSI/CDI is coupled to a GPS-style navigation source, but there's a whole set of issues related to navradio's GPS-slaved-mode there, which I will think about 'in the future'.
