I lessthanthree this analogy.
I am fascinated by the word lessthanthree. Even as a phone autocorrect, I wonder about the derivation.
Btw, agree, BeerSmith will help if you are designing your recipe, extract or all grain, by computing predicted gravity, color and bitterness. If you are consuming recipes it may help with scaling or substituting ingredients. And it's useful for tracking and inventory.
It's a tool, not an advice column. The blog and podcast might be useful if that is your desire.
It has more utility in all grain where there are more degrees of freedom. Especially because in all grain, even the recipe is severely impacted by system specifics like efficiency, batch vs fly vs biab, and kettle/tun size and dynamics like specific heat.
In extract, most of those variable are removed. The software is useful, but you are only benefiting from a portion of the value.
