QTR-Quadtone RIP

I'm just trying to create my own Ink Pattern Page [the page printed 
when in calibration mode - i.e.Ink Limits page] which I intend to read 
with an X-Rite Pulse (DTP20) in one straight swoop, instead of the 
individual spot readings I'm currently having to take, one at a time, 
very slow and painful.

Question:

I'm going to use a fine little program called ColorPort to produce the 
Target, I just need a pointer as to the figures I should use in the 
target production. Should I just open the original Ink Pattern Page in 
Photoshop and manually read the RGB values (which is what I need) or 
does someone have the values recorded somewhere; or am I going barking 
mad and it can't be done this way?

By the way I'm using UT2 (6 inks) inkset with a 1290.
