Select Columns for UPI,NUPI,USI and NUSI

Hello All,
 
Can someone explain on what basis we select indexes for the columns in the field.
Following is my understand:
UPI -> When we have Unique value, which is evenly distributed to all the AMPS. (The column selected for UPI looks like a field Eligible for USI as well. Then how to decide?)
NUPI -> Distributes the columns depending on the key on which it is defined.(This column has repeated values and seems to be eligible for NUSI. Then how to decide?)
 
Thank You.
