  I guess that would be the total times the [same] statement has 
been run _with the associated plan_ then.? :-)

  Get all invocations of that statement to implement with the same 
plan.? ;-)

  Seriously though... I seem to recall seeing that, for example, 
the /same/ statement run interactive [*firstio implicit 
optimization] versus batch [with *allio implicit optimization] would 
appear separately; the statements /explained/ with that difference. 
 For that scenario, adding the OPTIMIZE FOR ALL ROWS clause on the 
SELECT request would make the one statement appear only once, after 
having cleared the cache.
