I am looking to brew my third BIAB batch, and thought I might try my hand at cloning a recipe using BIABacus. I've tried to review most of the threads on conversion, to better understand the risks.

Could someone review my effort to convert this recipe:

Picking at gnats, you can enter 40.4 IBU into Section D instead of the VAW. That lines up to his recipe exactly.
