Thanks, Matt. Here are the linked best guess estimates together with the ranges in suffering-adjusted days (SADs) averted per $:
Animal Welfare Observatory (AWO):
European Chicken Commitment (ECC): 30 (4 to 126).
Cage-free eggs: 26 (8 to 67).
Mean: 28.0 (= (30 + 26)/​2).
Shrimp Welfare Project (SWP):
Humane Slaughter Initiative (HSI): 47 (42 to 52).
Sustainable Shrimp Farmers of India (SSFI): 299 (190 to 353).

Sociedade Vegetariana Brasileira (SVB):
Institutional meat reduction: 10 (6 to 14).
The Humane League (THL):
Cage-free accountability: 88 (17 to 351).
Better Chicken Commitment (BCC) accountability: 30 (2 to 89).
Mean: 59.0 (= (88 + 30)/​2).
Mean: 67.5 (= (28.0 + 173 + 10 + 59.0)/​4).
SSFI: 464–840 SADs/​$
190 to 353.
HSI: 43–53 SADs/​$
Nitpick. 42 to 52.
