QTR-Quadtone RIP

A friend showed me a profile for a particular printer which uses 7 inks. Here's part of it:

LIMIT_K=14
LIMIT_C=14
LIMIT_M=25
LIMIT_Y=18
LIMIT_LC=40
LIMIT_LM=25
LIMIT_LK=40

The "LIMIT" numbers express the relative ratio of inks (correct me if I'm wrong), but added together they exceed 100%: the sum is actually 176.  

I presume those numbers come from an examination of the patches on the QTR "Ink Pattern Page". 

Does the QTR engine reduce these to relative percentages ? 

K  = 8%
C  = 8%
M = 14%
Y =  10%
LC = 23%
LM = 14%
LK = 23%
------------------ 
Total:  100%

If so, would the following work just the same ?

LIMIT_K=8
LIMIT_C=8
LIMIT_M=14
LIMIT_Y=10
LIMIT_LC=23
LIMIT_LM=14
LIMIT_LK=23
