Mitch Steele's (otherwise) excellent book IPA concludes with recipes for historic, early craft, and modern IPAs. The grains and hops are presented in % per gallon. How do I translate that into lbs and ozs for a 5-gal batch size? For example, Harpoon IPA:
Pale malt 94%
Victory malt 4%
60L Crystal malt 2%
OK... 94% of what???
Similarly for the hops. The recipe is 9% Apollo at 65 min, and Cascade 19% @ 20 min, 35% @ 5 min, 36% @ WP.
Again, 9% of what? I don't know how to add 9% hops to the kettle -- I do know how to add 1.75 oz. of hops!
The recipe specifies "targets:"
OG 1.062
FG 1.013
ADF 77%
IBU 62
ABV 6.10%
The author implies that a specific recipe can be derived from those targets -- "a calculation can be made" for the grain bill; and "you will have to calculate the utilization for your equipment" to derive the hop additions -- but without the slightest hint what that means or how to go about it. Given the level of detail on other topics in the Appendices, it seems a rather glaring omission, and one that severely limits the utility of the book for inexperienced brewers.
This has got to be a common question -- is there a tutorial somewhere?
