No, you're 100% correct. Your grueling *6 hour* course (with lunch break, of course) definitely gives your claim more validity than my 30 minute google search in the NIH at lunch. Not quite sure it trumps Jon Sanderson's 6+ years of athletic therapy training, but maybe you just had a REALLY good teacher.
edit: Snarkiness aside - your 6 hour course gives you the tools to be a first responder - to not screw things up until the trained professionals arrive. This is why you are told to immobilize the head and spine and call 911 until someone with more education than a single day / weekend course can arrive to properly address the situation. You know, like someone with 6+ years of education and experience.
