Risk types and their conversions: 1 total risk (TR), 2 added risk (AR), 3 extra risk (ER). IY immunity, SL spontaneous lethality, xx target value (shown example = 10 %); converted values, max AR = [100 − SL]; TR xx = xx = 10 %; AR xx = [SL + xx] = SL + 10 %; ER xx = xx/100 · [100 − SL − IY] = 0.1 · [100 − SL − IY]
