      There are two separate issues.   One is the temperature of the
      water, and the other is the amount of evaporation (steam) caused
      by the heat.   <br>
      <br>
      The temperature cannot go above the local boiling point (we say
      100 C for our discussion).   Physically impossible.   <br>
      <br>
      And the test procedures do not allow the water temperature to be
      less than 6 deg C lower than BP.  So there is relatively little
      temperature variation allowed.  <br>
      <br>
      The steam (evaporation) issues can be discussed separately, with
      some stoves evaporating more water than do others.   That is a
      measurable variable that may or may not need to be in the
      calculations.   But measured water temperature is held quite
      stable.<br>

          <font size="2"><font face="Arial">Essentially there is only

          less than 94 C, and probably best to keep the temperature of
          the water at about 97 C.   <br>
          <br>
          But even a roaring fire cannot raise the temperature above the
          boiling point.   So the difference in the TEMPERATURE OF THE
          WATER is of little consequence, being about 3 deg C.   And
          remember that <u>the purpose or objective of simmering</u> is
          to maintain the temperature.   The purpose is NOT to minimize
          the amount of evaporated water, which is only a poor

                                            simmer efficiency might take
                                            some days, maybe weeks.  
                                            But not the months or years
                                            that this debate has been
                                            "simmering".   <br>
                                            <br>
                                            Remember:  A testing center
                                            that properly conducts
                                            testing using an endorsed
                                            but possibly flawed
                                            procedure is NOT a culprit. 
                                            The culprit is the testing
                                            protocols, <u>IF found to
                                              be faulty.   </u>And we
                                            hope that the testing center
                                            people (employees and
                                            leaders) who understand the
                                            technical aspects of the
                                            calculations will be among
                                            those who can help resolve
                                            these serious issues.<br>
                                            <br>
                                            Even those who developed
                                            protocols that are
                                            eventually shown to be
                                            faulty are not culprits.  
                                            Mistakes can be made.   
                                            However, the culprits can
                                            include those who advocate a
                                            protocol that he or she
                                            knows (or reasonably
                                            suspects) to be faulty.<br>
