QTR-Quadtone RIP

I am confused about creating an ink setup for my Epson 2200 printer 
using MIS UT7 inks for Condor BriteWhite paper.
In the User Guide I have determined my ink limit to be 85%, set my 
slider to that and reprinter the calibration page and found Lt gray 
to be 24% of Black.

Not I'm confused for the next step. The User Guide says in the Ink 
Density Calibration Section, "..QuadTone inks, this process is 
repeated for each lighter ink, comparing it to the next darker ink, 
calculating its density relative to that ink and then converting it 
to a density relative to black."

Later in the Creating a Non-Linearized Curve Section it says, "For 
QuadTone inks there can be more gray inks so you would repeat this 
process, setting the density of each gray ink relative to black."

My questions are:
1. Do I measure the 100% density for Lt Magenta relative to Lt Cyan 
(next lightest to next darkest) and find the % on the Lt Cyan stip 
that matches? Then find that density on the Black Strip and determine 
the percent? If so, why measure the Lt Magenta RELATIVE to the Lt 
Cyan? What does this do to know the % that 100% Lt Cyan is to Lt 
Magenta, wher is that used?
OR
2. Do I work up the lightness strips, Lt Magenta, Lt Cyan, Yellow, 
Magenta and Cyan and determine their respective 100% density values 
to Black to determine that % Black.

Thanks in advance,
