You'd need 83 grams of lye for that recipe for a 8% superfat soap, however, the % of goat milk is insane in that recipe. 73% of the oils is "water", so it's almost half oil, half "water". If it ever even set, you'd be waiting a year before it was ever usable. I'm pretty sure it'd separate and be garbage without ever becoming soap to be honest with you. Definately whack that GM down by a LOT, at least cut it in half since you're a beginner. You can cut it a little more as you gain more experience.
Personally, I think people need to make their own recipes. To start out, just try some cheapy oils to make your first soap to see if you like making soap. Then start research on what the different oils add. Use Soapcalc to help you out, it tells you how moisturizing, how cleansing, etc each oil is and what your final recipe will be like when made into a soap. Never go above 5% castor oil or 22% "cleansing" on the soap calc in your final bar. But, if people insist on "ready-made" recipes, make sure you get a good one. I'd never trust a source that expected you to add THAT much goats milk. Seems to me like they pulled numbers and oils out of their ass and typed it up without ever doing their research or even attempting to make the recipe they're promoting. :/
ETA again: The soap calculators are tools, not miracle workers. You need to know how to use them to your benefit. Very, very basically, you punch in whatever percents/oz/grams/lbs of each oil you want, how much fluid you want (by percent of oils or by ratio to lye), and how much you want it superfatted and it tells you exactly how much fluid to use and how much lye to use. You need to know how to use it to figure out what qualities each oil brings to the soap and what that means in a finished bar. Like I said before, never go above 5% for castor oil (calculators never tell you this, this is learned through experience or research, or by me telling you so, lol), and never go above 22% cleansing to start out. Again, calculators never tell you this, you have to learn it from somewhere. There are also variances to those rules, because you can increase your cleansing percent if you do a major superfat, but you need to have experience or research it to know how high you can take it without making greasy gloop. I haven't done the research on it, because it's simply not something I have ever cared to know (just don't see the need to ever make such a thing).
