I'm thinking (as Tami suggests) that a stove works best with a good 
active combustion. We should not try to slow the flame to lower the 
Power. Perhaps that can be done at Box-4. Use a heavy cast iron pot or a 
thin plate metal pot depending on the power wanted to get into the task. 
Lift the pot higher than optimum to lower Power or add more water.

Fuel quality and stove use patterns will vary. The purpose of what i 
suggest and what others have left unmentioned when using processed fuel 
in their stove tests. And it is true that we may not find the control 
over variables that we want - That's science. At least we will know 
precisely what the problem is.
