So I saw this...

But I wanted to do a extract version of it since this is my second time brewing. I came up with this but not sure if it is correct. What does everyone think?

6.15 lbs DME or 8 lbs LME

1 lb 2-row malt

.28 lbs crystal 45

.86 lbs Carapils

1 lb corn sugar

19.5 AAU Chinook (mash) (calculate how much you need based of AAU%)

WLP001 yeast

Steep all grains, corn sugar & calculated amount of chinook hops in 1 gal of 151F water for 45 minutes.

(calculate how much you need based of AAU%) oz 42.9 AAU Warrior (90 min)

(calculate how much you need based of AAU%) oz 6.1 AAU Chinook (90 min)

(calculate how much you need based of AAU%) oz 12 AAU Simcoe (45 min)

(calculate how much you need based of AAU%) oz 14.3 AAU Columbus (30 min)

(calculate how much you need based of AAU%) oz 20.5 AAU Centennial (0 min)

(calculate how much you need based of AAU%) oz 12 AAU Simcoe (0 min)

Ferment at 68F. Dry hop 2 weeks.

3.25 oz Columbus (Dry Hop 12 to 14 Days Total)

1.75 oz Centennial (Dry Hop 12 to 14 Days Total)

1.75 oz Simcoe (Dry Hop 12 to 14 Days Total)

.25 oz Columbus (Dry Hop 5 days to go in dry hop)

.75 oz Centennial (Dry Hop 5 days to go in dry hop)

.75 oz Simcoe (Dry Hop 5 days to go in dry hop)

I am unsure about a few things. If the LME amount would be enough and what it means by...19.5 AAU Chinook (mash). Do I just throw the hop pellets in the bag? Let me know how you guys think this looks.
