Wow, I see a diagram of boxes, lines and letters. I wish my brain could comprehend what you are doing. Kudos to you for having a working knowledge of that sort of stuff.
I gotta say, it's admirable how dedicated to fixing this problem you have been. I'm still so sorry for your loss, but you should be proud of the way you're reacting and putting in the due diligence to ensure it never happens to your animals again.
Also, like I said before, you may really be on to something. You could be a few years away from a hugely successful business. If you can get yours up and running with proven success, you could venture into a side business and watch it grow. You may be saving the lives of many reptiles and eliminating headaches and stress from many keepers in the near future...
