"The non-deterministic part is turning human instructions ("calculate the NPV over 10 years for X given Y") into Excel."

erm theres an NPV function built in excel.

Exactly!

The LLM just needs to make sure it uses it appropriately. Doing that bit is the non-deterministic part, but the NPV calculation itself is completely deterministic.

Youre not quite getting it, are you.

But humans non-deterministically use that or use a hand-rolled formula.

Humans dont enter numbers non-determinstically. WTF are you on about lmao.

Have you ever done anything related to corp finance/valuation in a professional setting? Highly doubt it.
