eye4clr, I've taken your advice to explore ink restrictions by chroma values. Please read on and advice if so inclined. With Mimaki SS2 ink @ 720x720 and the medias used I've never experience a decline in chroma values reading the Cyan and Magenta. IOW the values constantly climb even if just fractionally. However now that I also own and operate an HP 5500 Dye, I get values in the cyan and occasionally Magenta where Chroma actually starts to decrease. I've learned that a decrease in chroma value indicates basically a change in color and restriction should take place right before change. However I'm not certain if chroma has to go negative or to the point where the increase is fractionally small. I think I understand using L measurements for black as I restrict at the point before change in direction. Yellow set to most neutral CMY value as you describe (wildcard) or I may use density around 1.2 depending on density of Cyan and Magenta after established by chroma.
