The population-wide total IFR could be as low as 0.26% but it would depend heavily on the demographics of the people infected. If you infect 100 people under the age of 40 your IFR will likely be much lower than even 0.26%. If just 10 of those 100 are over 80 then it’s a totally different story. Not all diseases have such a high spread in the mortality rate versus age as COVID, which spans effectively 0%-20%. It makes discussions on the average IFR less useful than they might otherwise be.
