WSS, I would gather up a list of questions and call Gary at Wittlock Engineering and ask him about the Wecim software. After I purchased the Wecim software from Dynatorch they had me call him direct for any help I needed with the software. Thats how I learned about how long the software had been around and how it evolved. Since he is the owner and writer of the software it was just like dealing with Dynatorch. Like I said no one knows a product better than the person who designed / invented it. I just went to his website and he has a new demo, check it out maybe it will answer your questions about the oxy side of things that I am unfamilar with.
