It seems that all I do is ask questions...

How does one evaluate OC sprays?
I've heard that "5%" or "10%" are meaningless (percentages of what?)
I have read to rate OC by "Schoville Heat Units" (SHU). Some "authorities" say at least 1,000,000; others say 1,500,000.
I recently received a catalog that advertised 2,000,000 SHU.
What's the story?
