The units are meant to guide the RGB gains, such that, if more red is required
to better match the target chromaticities, then that's what is shown. I'm not
familiar with the algorithms used by dispcal to make the suggestions. But, for
sure, it's no more voodoo than that.

Subject: [argyllcms] Probably a simple question
I have a bit of a simple question, one that I haven't found a good
(non-technical) answer to in here.
This is in regards to display profiling via dispcal. As most of you
know, dispcal can calibrate brightness on an LCD monitor. What I am
having problems finding is something that says what the numbers should
be (menu items #3 and #4 specifically). I am presuming that the "R+ G--
B+" bit on the reading line are saying something to the effect of "Red
is high, Green is very low and Blue is high". What about the brightness
value - what SHOULD it be; what units is the readout in (is the readout
in any units at all)? What about the contrast level.
I know it might be a distraction here, but I think it would be quite
useful for a "HOWTO" guide to be created that details in non-technical
terms exactly what steps to take, in what order, with what guidelines to
follow and numbers to target in order to get a good profile.
I'm willing to write such a paper if someone else is willing to vet the
information for technical accuracy - proofread if you will.
