<DIV><FONT size=2 face=Arial>It is not really so important to me, all these
details. A good stove will do well whatever the details, and our
Wonderwerk is a good stove. When and if the test you support is available
the Wonderwerk will do well when tested by it, as will the other four stoves
Aprovecho has developed, and other good stoves everywhere. The CO and the
PM are measured directly with precise instruments. There are no questions
here and good stoves will show their quality. If you have a test that will
show something different about the Wonderwerk stove, then I say bring it
on! The Wonderwerk stove is ready to rumble when and if ever you
are! I have spent the last two years developing a superbly clean
burning stove. Where is your test?</FONT></DIV>

<DIV
style="BACKGROUND-COLOR: rgb(255,255,255); WIDTH: 100%; FONT-FAMILY: Calibri, 'Slate Pro', sans-serif, sans-serif; COLOR: rgb(31,73,125)">I
think this needs less correction that you offered. There is (as far as I know)
no WBT 4.2.4, but there is a WBT 4.2.3 spreadsheet update bearing the number
4.2.4. It is on the GACC website. </DIV>
<DIV

<DIV
style="BACKGROUND-COLOR: rgb(255,255,255); WIDTH: 100%; FONT-FAMILY: Calibri, 'Slate Pro', sans-serif, sans-serif; COLOR: rgb(31,73,125)">The
difference is that WBT4.2.3 is a test protocol and there is an accompanying
spreadsheet. From what I see from Berkeley, they say the Python software
reproduces the math and outputs of what is contained in the 4.2.4 spreadsheet,
which is different from the 4.2.3 spreadsheet. </DIV>

style="BACKGROUND-COLOR: rgb(255,255,255); WIDTH: 100%; FONT-FAMILY: Calibri, 'Slate Pro', sans-serif, sans-serif; COLOR: rgb(31,73,125)">There
are more than 660 differences mostly resulting from the deletion of entries
(sort of like example data). It has been removed. </DIV>

<DIV
style="BACKGROUND-COLOR: rgb(255,255,255); WIDTH: 100%; FONT-FAMILY: Calibri, 'Slate Pro', sans-serif, sans-serif; COLOR: rgb(31,73,125)">There
is no longer a tab explaining what the differences are (what was changed from
the previous versions) and there is no separate document on the website
explaining the changes. There are other documents explaining some of the
previous changes between previous version but not the latest one so you are on
your own in that regard. </DIV>

order to see what the differences are in the result, I fill in different
version of the spreadsheet using the same inputs. In that way you can see the
effect on the calculated performance from different versions as the sheet
evolves. </DIV>

<DIV>The numbers I reported to you are calculated using equations in the WBT
4.2.4. We do not use a spreadsheet to calculate those numbers and instead
use a Python code we developed to read it our raw data. Also, we do not do
the carbon balance method to calculate PM2.5, but instead use the total dry
fuel consumed method (fcd). Using Python helps us also analyze our
ultra-fine particle data. Before you left, we cross checked our numbers with
the WBT 4.2.4 spreadsheet (that we double checked for errors) to make sure
nothing looked amiss with our Python analysis. This is something we always
to to ensure data was imported correctly.</DIV>
