Looks more spread out wavelengths, therefore raising CRI?

I have lined up the wavengths common to both (Hg & Na), so yep, CMH has plenty of red and the 589nm sodium yellow-orange is much more pressure broadened almost like HPS.

The intense green line in the center of the CMH spectrum is from Thallium (535nm). Not found in standard metal-halide lamps, Scandium is used instead.
