I don't know that we'll need this logic for an "unprovoked" transmission.  We
needed it in histograms, since the data was buffered (in an intermediate tally)
on the browser. For this data, we currently don't buffer it anywhere... so we
don't currently need it.  It is fine to leave the logic (I can imagine we could
do buffering), but the explanation abotu after a page load is not really
applicable.

Deleted this.
Done.
