of the data. However this only applies within a single query pattern i.e. { } so depending on the structure of your
query you may need to do some manual reordering. Also if inference is involved then that may interact.

This is from memory, so I could be wrong, but I believe that TDB's stats.opt file from which the statistics are drawn is
_not_ updated on updates, but only on rebuilds or via the tool tdbstats. So you may want to update that to see if it
makes any difference.
