The bug is in your own code: your resid() function always returns the 
same result:

 >>> print(randomtest.resid(numpy.array([  60.,   180.,    22.,    22., 
     0.2]), [randomtest.sorted_list]))
[  1.9845187   32.64266682  26.29888414 -16.90617247  -5.73287752
   -0.58050037   2.75023576]

 >>> print(randomtest.resid(numpy.array([  6.,   18.,    2.,    2., 
0.]), [randomtest.sorted_list]))
[  1.9845187   32.64266682  26.29888414 -16.90617247  -5.73287752
   -0.58050037   2.75023576]
