Vasco Grilo🔸 comments on Welfare ranges per calorie consumption

[Vasco Grilo🔸]

This would only be 100 % correct if the welfare per time of the practically maximally happy life as a fraction of the welfare range is constant across species.

In this case, “maximum welfare of a chicken-year”/​(“maximum welfare of a chicken-year”—“minimum welfare of a chicken-year”) = “maximum welfare of a human-year”/​(“maximum welfare of a human-year”—“minimum welfare of a human-year”) ⇔ “maximum welfare of a chicken-year” = (“maximum welfare of a chicken-year”—“minimum welfare of a chicken-year”)/​(“maximum welfare of a human-year”—“minimum welfare of a human-year”)*”maximum welfare of a human-year”. Since “welfare range of chickens” = (“maximum welfare of a chicken-year”—“minimum welfare of a chicken-year”)/​(“maximum welfare of a human-year”—“minimum welfare of a human-year”), “maximum welfare of a chicken-year” = “1 AQALY in chickens”, and “maximum welfare of a human-year” = “1 QALY”, “1 AQALY in chickens” = “welfare range of chickens”*”1 QALY”. So, given the condition I mentioned in the footnote, one can get the welfare in QALYs mutiplying the welfare in AQALYs by the welfare range.

Got it, thanks. For those following along at home, I misread your footnote and the graphs I made do not reflect the condition in the footnote.
