For Matthew's data, I get a slightly different Super Model:

Code:
       coeff       change     value    sigma

  1     IH         +0.000   +735.72  202.978
  2     ID         -0.000   -520.59  153.884
  3   & HHSH4      +0.000   -600.58  175.044
  4   & HHSH5      -0.000   +281.81   81.956
  5   & HHCH5      -0.000   +211.24   60.775
  6   & HDSD       -0.000   -281.12   44.287
  7   & HDSD4      +0.000    +16.88    4.663
  8   & HDSH2      +0.000   -885.09  270.273
  9   & HDSH3      -0.000   +370.05  112.750
 10   & HDCH3      -0.000   +228.06   71.055
 11     NP         -0.000   -364.09  196.648
 12     CH         +0.000    -82.02   39.926
 13   & HXCZ       -0.000  -1009.76  367.233
 14     ME         +0.000   +298.88   68.782
 15     MA         +0.000   +358.46   77.630
 16     TF         +0.000   +220.96   48.128

Sky RMS =  16.58
Popn SD =  18.88
I also get these recommendations for polar axis alignment:

Code:
Polar axis settings:

    ME     MA

  +299   +358       current setting
   +88     +0       refracted pole
   +48     +0       minimize field rotation
   +40   +790       minimize unguided declination drift
  +175   +754       minimize unguided total drift

The polar axis is currently 299 arcsec above and 358 arcsec
to the right of the true pole.

To reach the refracted pole, lower the polar axis by
211 arcsec and rotate the mount anticlockwise by 431 arcsec.

To minimize field rotation, lower the polar axis by
251 arcsec and rotate the mount anticlockwise by 431 arcsec.

To minimize unguided declination drift, lower the polar axis by
259 arcsec and rotate the mount clockwise by 520 arcsec.

To minimize unguided total drift, lower the polar axis by
124 arcsec and rotate the mount clockwise by 476 arcsec.
