I got double that on Brewer's Friend recipe builder. Cut the hops in half - they were using leaf hops for one - and things worked out.
They know you can't reproduce it on your equipment. Still, there's more than enough information there to hack the recipe. One thing missing is the exact yeast strain. They likely have a house strain and one of the major labs has likely cloned it but it's not the exact strain. The biggest missing piece of knowledge is their water and what they do with it. But we can get close from this and I'll likely try - I like a good Pale Ale, IPA is generally a bit over the top for my palate and edges over into harsh.
I'd like to send her a bottle of my Common but that's a digression. One thing I've found recently that really improved my hoppy beers and pretty much changed my "brewing priority order" is dechlorination. Now, right after sanitation, is making my water is free of chlorine and chloramine, using Campden tablets. Once I started doing so, I got a good Saison for the first time. Everything else has had better malt profiles. Next up is buying water from the local grocery store: Those big water machines in the front of the store are RO filters, the water costs $0.37 at my local King Soopers and is a blank slate for building up my brewing liquor. That will be how I try the Sierra Nevada clone, by building up the water from null using the "Light and Hoppy" profile on the site.
Bloody great attenuation and high sulphates? So thats what your trying to replicate with your keg hop...
