Commercial operations test the emulsion at several stages of the
process, and adjust later steps (generally, the ripening) to get
consistent results. Absent this feedback loop (which I presume is
the case with home emulsion-makers), you do need very accurate
temperature control (as well as accurate control of timing,
concentration, and flow rate of additions) to get consistent results.
