Larry,
Can't say anything about the accuracy of data.
But as far as the linearize scripts they are not built for any particular device since they just
look at txt data files. So they do depend on the software that writes the data file.
The scripts look of data that is arranged in columnar form. They are quite flexible in the actual
format and attempt to decipher what ever is there. The -out.txt file usually shows what it
thought the data was.
I don't know the Munki data format you are looking at but if you'd send me the data that didn't
work I'll see what sense I can make of it. (btw, in general its always best to show what you
have rather than just saying it doesn't work)
Thanks,
Roy

Just to be clear, all the evidence I see is that the data is accurate. In fact, I'm able to use the i1 21x4 patches if I use the spot measurement. I figure it's just that because most people who are interested in linearization .quad files probably have i1 devices, so the tools that Roy developed are designed for the i1.
I'm sure that PPE will make using the Munki much easier. However, I can confirm that it is feasible to use the Munki to linearize .quad files.
My Aurora Art Natural is so far from linearity (looks like one of those quadratic functions we had to plot in math class years ago) that QTR-Linearize-quad won't linearize it. I may have Inkjetmall profile it, but that would be like having someone add a supercharger to a Toyota Tercel.

ColorMunki software (color-picker) exports some
messed up data. It’s not the quality of the sensor (they
are basically the same between the two devices) but it’s a
difference in data output from the software.
PPE will be back on sale
shortly.

Finally got it.
QTR-linearize seems to be
optimized to read i1 data. To use Munki data I had to
borrow a .txt made by some one else's i1, then copy and
paste my L, A, and B values in place of theirs. Once this
was done, I got a .quad file just fine, and linearity is
improved greatly.
