I'll take a shot at mapping these.

datastore_v3.Put will result in one Entity Put + One Index Writes for each
index field that was added (in case of new records), or Two Index Writes for
each index field that was modified (an index delete for the old index value
and an index write for the new value).

datastore_v2.Get is equivalent to Entity Fetch

datastore_v3.RunQuery is equivalent to a Query.

It seems that app stats was written to reflect on the costs in the old
pricing model.  It'll be nice it is redesigned to be consistent with the new
pricing model.  I don't know who supports this tool, but can anyone in the
GAE team tell us if there are plans on updating it?  Is app stats open
source, allowing anyone to take a stab at it?
