If you are unsure how well data is going to be distributed when moving from one table to another (and one PI to another), you can use this query to analyze the distribution:

select hashamp(hashbucket(hashrow(new PI column(s))))
        (named vproc), count(*)
from tablename
WHERE any condition(s) that might apply
group by 1
order by 1;
