"<br class=""></i></div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>To emphasize: I am in full accord with this “Resolution 1”. I am no way disputing it - and don’t believe I ever have. In fact, my complaint is that the Tier credit given through what we have called the “Denominator Equation” (DE) rather shortchanges those in the lower tiers who may have (or be able to produce more) char. That is, these lower tier stoves could move higher in the Tier rankings with less char than is now allocated to them, using almost any allocation approach other than the DE.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>I am afraid that most of the concern on this list about the DE is based on thinking that the DE is incorrectly reporting test efficiencies. It is NOT. It is reporting what <u class=""><b class="">would have</b></u> happened if no char had been produced. I have stated that I couldn’t understand why the DE is stating an <u class=""><b class="">inefficiency</b></u> (not efficiency) larger than is measured. But this is because I too was thinking too much on the existing just-obtained lab results. Stove inefficiencies will indeed grow with no char - as can be seen in the high rankings for char-making stoves - and few high rankings, if any, with stoves producing no/little char.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>I can now reproduce the Tiers without using the DE (but still using the same lab results) - but I can’t yet justify this or any (other than the DE) approach. I may be getting closer. Glad to include anyone interested in the topic (which obviously is neither trivial nor unimportant). But I still need more time to compute different things.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span></div><div class="">Ron</div><div class=""><br class=""></div><br class=""><div><blockquote type="cite" class=""><div class="">On Feb 18, 2017, at 11:06 AM, Traveller <<a href="mailto:miata98@gmail.com" class="">miata98@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Xavier: <br class=""><br class="">As an economist, I agree with you sunk cost has no consideration.
