Does your software estimate FWH?
I've been using TastyBrew.com recipe calculator for years on my recipes and it has a pretty good estimate for FWH. You can experiment with it by changing 60 min boil to FWH, etc.
But I have heard most folks say the 'perceived' bitterness from FWH is like a 20 minute hop addition. I find the target IBU important especially if planning FWH as the main bittering hop in a beer. I usually focus on this "60 minute hop" IBU to set the balance for the beer. 10-20 malty, 20-30 balance, 30-40 pale ale, slight bitter IPA, 40+ IBU, IPA's and highOG.
The Zombie Dust is focused on just enough "60 minute" bitterness to balance the rich malt (from specialty grains and yeast) in this beer. Cool part is you can get that with FWH and the bonus of '
'perceived smoothness' of FWH. Good stuff.
