How does the calculator handle option pool expansion?

The `simulate_option_pool_expansion` tool calculates the additional shares required to reach a target post-money ESOP size, specifically showing the impact on founder ownership.

Can I simulate a down round?

Yes. By using `calculate_anti_dilution_impact`, you can evaluate how a Broad-Based Weighted Average anti-dilution clause will adjust conversion prices when the new share price is lower than previous rounds.

What information do I need for a round simulation?

To use `calculate_round_dilution`, you need the new investment amount and the pre-money valuation. You can also optionally include a target option pool expansion percentage.
