## Error in Handbook?

Ok so I've been looking at this for 30 minutes trying to prove that I'm wrong. Maybe someone can explain it to me.

http://www.thefreshloaf.com/handbook/san-francisco-style-sourdough [1]

In the Sourdough page it shows the following formula:

White flour: 100%

Salt: 2%

Water: 72%

30% of the flour is in the starter. (I’ll give two recipes, one for starter at 100% hydration and another at 60% hydration)

Then you have the absolute numbers:

White flour: 500 grams or about 4 cups

Salt: 10 grams or 1.25 tsp

Water:

- Using a wet starter: 210 grams or 1 cup MINUS 1 Tbs
- Using a stiff starter: 270 grams or 1 cup +3 Tbs
Starter: Two options

- Wet starter (100% hydration) 300 grams or 1 ¼ cup
- Stiff starter (60% hydration) 240 grams or 1 cup

Assuming a wet starter wouldn't that make 650 grams flour and 360 grams water making 55% hydration? Not the 72% in the formula. The formula even states 30% flour in the starter so I'm thinking the flour is supposed to be 350 grams.

What am I missing?
