Hi,
I like the clarification but I think that:
A higher <literal>leaf_fragmentation</literal> indicates that the
physical order of the index leaf
pages increasingly deviates from their logical order.
Would be cleaner than:
The higher <literal>leaf_fragmentation</literal> is, the less the
physical order
of the index leaf pages corresponds to the logical order we would have
just after
a <command>REINDEX</command>.
