Unique is dirty but not as dirty a Bulleye
The new formulation is much cleaner than the old formulation. I don't know when you did your tests by several years ago Unique was reformulated and made much cleaner burning. However it is still dirty.
As I stated above the 2 shots was to establish a starting place.
When I get more data I will post.

We did our testing the other month, the Unique was probably 2 years old or so give or take, the container says something about a new formulation or whatever is this the one you're referring to?. I just wasn't very happy with how dirty it was is all, but we aren't having any problems with the clays and they are shooting really nice with a pf of around 125-130...
