I shot the battle in the bluegrass for 8 of its 10 years and don't remember minor ever winning or even sitting in the top 5/10 with any regularity, and this was a SS-PROD match with balanced stages. Perhaps look into the history of that west coast SS match every year for more comparisons (lots of GM in SS at both)
When the top 18 shoot major at locap, and they are the big names, I'm going to say it was balanced or major friendly.
Now, and average shooter may do better with the extra rounds as we may take more makeups.
