Any type of comparison between reactors using MMW, watts per liter, or % of Faraday can all be misleading based on how you measure the LPM and how much moisture is in the HHO. The methods used by most are inaccurate at best so comparing between the results of others is somewhat useless. It should be used to compare with yourself when making changes to your system and you must be consistent in how you measure. Just remember that moisture takes up a lot of space compared to gas so your results could just be showing more moisture instead of more gas output unless you are using a dryer to remove the moisture. What you think is an improvement might be just the opposite with just more moisture being created and no more or less gas.
