Providing child benefits (which can even have a negative impact): -$41,977 to $18,411
If I look in your spreadsheet the negative impact appears to come from limiting the benefit, i.e. reducing it (quote below). So providing it was presumably positive?

I am just wondering about mid-career professionals: Could one not easily abandon the focus on elite universities for this group?
The focus on top universities is to access the people there. Mid-career people (outside of researchers) are no longer at university, so they are not primarily accessed through university groups. I don't think anyone is applying a harsh undergrad filter to people with strong track records in their field (at least, I'd expect most EAs to be less credentialist that is the norm for e.g. government hiring), and I'm confused why you would think this was the case.
Are you sure this is right?
The founder, Kevin Esvelt, who was not present with us, has a PhD in international relations with a focus on foreign policy-making. Before founding SecureBio, he was concerned about the lack of preparedness for existential risks from AI.
If you click the link it says he has a biochemistry PhD, and my impression is he has always been more of a bio guy (arguably the bio guy):
Kevin M. Esvelt is an associate professor at the MIT Media Lab, where he leads the Sculpting Evolution Group in advancing biotechnology safely.
He received his Ph.D. from Harvard University for inventing a synthetic microbial ecosystem to rapidly evolve useful biomolecules, and subsequently helped pioneer the development of CRISPR, a powerful new method of genome engineering.
