I can offer up this bit of wisdom, not sure if it will help. Lagunitas Little Sumpin clone recipe has some minute amounts of bittering hops in a 5 gallon batch. They used 3 different hops. On the brewery level it makes sense as they probably pitched in large bundles or set amounts of extract, on the home brew level it does not make sense to add several grams of a bittering hop you can't discern from another hop. So when I brewed it I just used one bittering hop for all. The CYBI folks just scaled down from what the brewer told them without parsing it to us home brewers.
So the answer is gut, at least that is what I would do.
