I don't know if these add anything of interest, but I am a Sunny 16 man with my rangefinders (Zorki4 -> Kiev4A -> M3), and although I have a incidient/reflective meter with me, I rarely take it out of my bag.
Light through window from setting sun and scattered clouds made me expose XP2 Super at 1/250sec f5.6 with Jupiter 8 on the Zorki. PP done (on a very poorly calibrated monitor) to the center of the image, where the dragging shutter curtain caused an uneven exposure.
Same exposure as above, with APX400 in Moskva5
Weak indoor lighting, 1/15sec, Jupiter 8 at f2.0, Pan F+ at 50ISO.
Stage lighting, 1/125, f2.8, Neopan 1600.
Stage lighting, 1/125, f1.4, TMAX400
The concert settings I must admit are influenced by experience with shooting the same locations with a DSLR, but with a little experience, I feel confident in most lighting situations with a film with a reasonably forgiving exposure latitude.
