---Dave, I was trying to point out there are many variables included
even in the testing, even of objective tests. I run a flour sample
here (myself) and do all the sample prep one day and do it again the
next day and get different numbers (vitamins B1 and B2 for instance)
each day. New variables the next day? Sample changed? Usually the
numbers are close but what do you do when it comes time for
disposition esp when numbers are not close? Maybe average, maybe
rerun sample, maybe get another sample? Maybe re-write the specs.?
Maybe throw out one for some reason. Anyway experimental design will
be important in the brewer tests. Dennis

need for testing in my mind, not with someones hard found recipe, but
with a mutually agreed to compost and food of some kind. Unless we
can get information about the variability of these machines then
we're all on our own a bit and progress, much needed, will be
difficult. It's hard to extrapolate to new situations unless we nail
down the variables one at a time. I think the strength of this forum
is found in combining our sometimes expensive experiences. I've
spent a couple thousand on testing myself without any product except
that I teach. Those of us in the non-commercial world stand to gain
the most from sharing. If I can pay for only one report and get the
answers from 5-10 others I'd consider it money well spent.
