Sounds about right. I'm impressed with the operating parameters of that system. It seems as though you've managed to develop some modifications of your own in order to get some of the read out and results. Allways continue to devise methods that provide as much accuracy as possible! That separates you from thousands of those with unsubstantiated claims and or ridiculous means in which to quantify or "prove" their results. My Kudos to you and my I encourage you to continue to develop accuracy in your testing.
Stay in touch. I'd like to know more about your testing and experiments.
Our testing at the labs got moved till Feb of 2010. I have much data to compile on our system and I was looking forward to testing. Now I guess next year.
