The Linearization does work with 51 steps but since the step values are
closer its a little more sensitive to lack of separation betweem the steps.
For the most part I think 21 is plenty.  Compared to color charts that are 
commonly used this is way more data points per dimension -- 1000 patches
for color in 3 dimension is only 10 point per dimension.
