Historical Performance Information per SQLID

A) Can this column be relied on as being the total elapsed time for  a query?

DBA_HIST_SQLSTAT

ELAPSED_TIME_TOTAL NUMBER  Cumulative value of elapsed time (in microseconds) used by this cursor for parsing/executing/fetching

In other words, If I am interested in the performance of a query when I know a sqlid, is this the best place to go to get it's past performance?

C) If not, what is recommended?

Howdy, Stranger!
