If you are going to use this method of using create table as to limit your table size, then watch for redistribution of data when you change the PI.

<< Hint: Add a csum(1,1) or the like sequence field to your select so you can reliably pick up what records belong on page x of the output - also make the PI of the table this sequence field so that you are assured excellent distribution regardless of the fields in the query >>

This can result in a significant performance impact.
