Let me explain it in layman's terms for you Dan.

I gave you some suggestions to improve your radio spot, right?? Okay; then you came back and said that the spot has increased your business sales already to which I responded that my suggestions weren't necessarily needed after all. Your sales have increased so apparently what your doing is good - 'right', ie., a step in the right direction. I suggested that if the tune was "even catchier" then sales might be "even better". If you want to still take my suggestions to heart (do them) then GREAT!

But all I was trying to say Dan is that improving the 'professional' aspect of the radio spot, ie., making it better (catchier tune, etc.) could possibly increase your business sales substantially (a great deal more than the increase you've seen already). But since sales have increased some already through the original spot - you're indeed doing something right, right?? I'm just trying to give you some suggestions to help your sales even further.

Best regards,
Mike
