Hello Sinardy
PCTUSED means that:
After a block was filled with records and the free space in the block
is less then pctfree the block is no longer available for further inserts.
If however, the data falls beneath PCTUSED the block became again
available for inserts.
In your example, block will never again became available, even if empty,
because: After a data block becomes full as determined by PCTFREE, Oracle
does not consider the block for the insertion of new rows until the
percentage of the block being used falls below the parameter PCTUSED.
