Looking it all over again, I think instead of laboriously trying to rote memorize 80 styles, I will start with the 12 recipe styles. 12 months ought to be plenty of time to really dig into each one, including writing score sheets on each with a classic example, researching, writing, and brewing my own recipes.
Meanwhile I'll chunk away at the others, maybe grouping them as they compare to the big 12 so it makes sense in my head.
The other side project will be nailing down my knowledge of techniques, ingredients, and troubleshooting.
