cluster ratio get affected when you are deleting and inserting lots of

it is the alignment of column data in index in accordance with sort

only one index among many indexes on single table can have 100%

REORG will help you bring up cluster ratio
RUNSTATS first
REOGR and then
RUNSTATS again
It is possible for more than one index to have a cluster ratio of 100,
but it would be somewhat coincidental.
For example suppose you had a clustered index on the primary key,
which was vendor number (defined as an identity column), and another
indexed column (not clustered) which is the timestamp of when the row
is inserted (current_timestamp). Then both of these indexes could
easily have a cluster ratio of 100 (percent).
