Here is the recipe I plugged it in to Beersmith and got the correct results,
I think He uses whole leaf hops ! that will change a few things and don't forget to set you mash, I think a single infusion (full body) will be really close to what you may need.
Up at the top of you recipe window in Beersmith there is a drop down that will let you select what type of brew you are doing. ie: extract, Partial mash, or All Grain
Hope this helps
