The 2nd query I posted is returning the data I want (max number of sessions

It's interesting that:
ALTER SYSTEM SET OPTIMIZER_FEATURES_ENABLE='12.1.0.1' SCOPE=BOTH;
...has the query returning the correct results, as inferred by Jonathan's
blog post linked in a previous response.
I'm getting the same incorrect grouping as you with my 12.1.0.2 DB, and this
setting appears to be a workaround, although with the distinct possibility of
other side-effects.
