CHI SQUARED TEST ON ANALYSIS
  .748 <   .660 <  1.208
  (LOW)             (HIGH)
DOES NOT PASS AT THE 5 % SIGNIFICANCE LEVEL
A STD. ERR. OF UNIT WGT. BETWEEN 0.5 AND 2.5 IS
CONSIDERED SUITABLE FOR MOST APPLICATIONS

=============================================
Changed error estimate of the original 100147 control point to 0 0 and 
commented out the ARRA control for this point as per Gary Knoffs instructions:

"T22NR09E, 100147, the ARRA control should probably be * out and the
original control used, but as 0   0 and Coco. Cnty. BLM BC (look at
T22NR08E, 700140).  The ARRA elevation for both of these points can be used
(6484.0).  I don't know that if when this was done back in 1999
and the Coconino County control data was entered it may have failed and the
estimates were put in at   3    3, but for T22NR08E they were
held fixed."

Holding this position fixed did not cause the twp to fail:
