Spare,

You don't have to apologize for the post.  I'm just trying to make sure info is clear.  There are directions on the bottle for using the polishes.  If all you do is apply the polish to your Inferno without first taking it to 400grit, then it wouldn't surprise me if it went straighter, because in a sense you are adding more polish on top of other polish(already on the ball).  Make sense?  I would imagine a similar thing if you just applied Rough Buff to your Blazing without first taking it down with sandpaper or scotchbright.  The polishes can be used to adjust your balls reaction.  Take a look at the back of the bottle.

Hope this helps.
