Looking at what I called the "Sample" files, I see that they are not in the same format as 
the files from my reading of the 21 step not-random step wedge. One file I used 
successfully with Spyder3Print looks like this:

BEGIN_DATA_FORMAT
SampleID	GRAY	LAB_L	LAB_A	LAB_B
END_DATA_FORMAT
NUMBER_OF_SETS	21
BEGIN_DATA
1	0	93.47	0.95	-5.24
2	5	90.32	1.05	-4.97
3	10	86.37	1.01	-4.67
4	15	82.67	0.85	-4.43
5	20	78.93	0.84	-3.94
6	25	75.11	1.23	-3.45
7	30	70.66	1.01	-3.77
8	35	66.64	0.68	-3.38
9	40	62.66	0.84	-2.49
10	45	59.03	0.85	-2.39
11	50	54.67	1.05	-2.55
12	55	50.07	0.99	-2.01
13	60	45.20	1.29	-1.51
14	65	40.02	1.14	-0.99
15	70	35.31	0.97	-0.97
16	75	29.48	0.88	-0.28
17	80	23.68	0.83	0.04
18	85	17.52	0.65	0.39
19	90	12.26	0.45	0.71
20	95	7.17	0.11	1.50
21	100	2.26	0.00	0.24
END_DATA

I hope the formatting shows properly.

Here's what I did to make that file from the 21 step not-random printout:

In Spyder3Print, under Tools:

First, do the Calibration using their supplied white target.

To make a file for icc profiling, go to Tools/Measurement

1. set a name for the export file. I prefix mine with my initials, MR, so I can tell the ones 
I've made from the many other profiles that show up in Photoshop drop downs. QTR will 
also put its prefix in front, as it does with profiles supplied with QTR (as QTR - Grey Matte 
Paper) so mine end up as QTR_MRxxxx.

2. check QTR Override and press 'CreateICC'

3. make measurements

4. Press Done

5. Drop the file in the Spyder3Print 3.0/Data/Export folder on the QTR-Create-ICC 
droplet

6. Move the created .icc file to ~/Library/ColorSync/Profiles or to another Profiles folder.

Mac, Tiger. QTR 2.4.3. Hope that helps.
