Thanks, JD. Great point on the known and unknown! I didn't think of that option even though I use to do that. I will bring this up one more time and tell them I can differentiate the groups -- maybe that will help.
P.S. I complete agree with you I fought, and unfortunately lost this battle. I'm pretty sure the majority of them won't be tracked either. I'm having to slowly ease them in to the world of marketing metrics...
I wrote a couple of types of page templates. One such template will bypass the form if you're a known lead in the system, and present you a button instead. It's not all the difficult, but there's a lot of JS code, which I learned while writing this template.
