It is good to see others on the same wavelength. You are on of those people. Initially, you sounded "fresh out of school niave". You are not niave. And yes, reversal design is unacceptable if you are fairly sure that the intervention has had a positive impact. Also, you are one of the few folks who takes the time to respond to sincere responses. I am paid to provide solutions. I am very good at it. I suspect that you are too! Rock On!
