safebrew has answered your last question perfectly so let's take a look at your file...

Okay, that looks great J . I haven't double-checked your weights, times etc against the original NB recipe as I assume what I see on the left of Sections C and D will match the original NB recipe. I see that either you or someone else above has guessed at the AA% of the hops and guessing is pretty much all we can do here and what we must do. Not telling you the AA% of hops originally used is one of several major errors in NB (and many other) recipes unfortunately.

All yu can do in these cases, is look up one of the sites listed here and then use the average AA% of the relevant hop.

Check the above but also definitely make the following correction...

The other critical bit of info that is either very hard or impossible to find in most published recipes is the VAW. Your file says 18.94 L (5 US gallons.) From the research done on this site, we interpret a Northern Brewer recipe as being 5 gallons into the fermenter plus 0.5 gallons of kettle trub. In other words, 5.0 VIF plus 0.5 KFL = 5.5 VAW.

So, change your first line of Section D to 20.83 L or 5.5 US Gal.
