Comment (by jinmei):

 I'm assuming it's better to review this ticket once #2136 is
 completed.

 BTW, I guess this is the stats counterpart of #2196.  If so, I suspect
 we should discuss what we should actually do about the "differential"
 thing before proceeding to the actual implementation/review.  As
 briefly discussed in #2196 the proposed behavior doesn't make much
 sense to me.  Michal seems to have the same/similar concern.
