No, "reload" does not include initial load.
"reload" - Any PIN of an object that is not the first PIN performed since the object handle was created, and which requires loading the object from disk.
"First_loads" = pins - pinhits - reloads

OK, fair enough.
Something to consider: the concept of "reload" probably
also includes the concept of "initial/first load". I don't know whether this is the case for certain, but one way to check might be to query the number of items in the V$SQLAREA (i.e. "select count(*) from v$sqlarea"). After all, each of those entries had to be loaded (a.k.a. "reloaded") at least once, I think...
