+1 on using different titles.  No opinion your particular suggestion,
but the TOC on the tutorial needs to be consistent as well.

I think we should have index entries for function names, aggregate or
not.  Perhaps <primary>avg</primary><secondary>aggregate function</> ?
Hmm, or maybe the other way around, so that all aggregates are listed
together in the index?  Not sure.  (but surely we don't want to have all
functions lumped together in a single "<primary>function</>").

For some reason I don't like <primary>average</><secondary>avg</>, but
then I don't like the current <primary>average</> either.

Confusing index entries favor no one.  +1 for fixes you can suggest.
