0 - 3 of 3 tags for all amp

Hi All,
I am updating my tables based on primary index, however from the DBQL I see all the amps are active. Could someone explain, if this is expected ?
 
Cannot post the table structre for confidentialy reasons.
But it's like:
MyTable
(Column1 CHAR(10)
,Column2 CHAR(5)
,Column3 INTEGER
....

Hi There,

If i  have created nupi on the sex column, definatly it has skew ness. Think those two amps are filled (while others are free), we got one more record in to the table. what will happen?
 

My assumption is the record will not insert, as per the rowid/rowhash.
Am i correct?
