Russian roulette might be an unfair comparison, but it may only be one order of magnitude different to this virus IFR.

With probability a number between 0 and 1, percentage is between 0 and 100.

From the study in your source [1] the P(death|infected) = 0.005 And Russian roulette P(death | play) = 0.16

In percentages:

Covid19 - IFR = 0.5%, Russian roulette = 16%

From this calculation based on the recent New York antibody study [2] the average IFR across all age groups is 1.31%. (0 + 0.017 + 0.067 + 0.13 + 0.45 + 1.26 + 3.16 + 5.4)/8 = 1.31%

This is a much higher IFR than flu or H1N1 (IFR was 0.02% in 2009, 65 times less).
