I might have to bring it up to a minute or two before I’d give you that—I perceive the exponential growth in disutility for extreme pain over time during the first few minutes/hours/days as very, very steep. Now, if we posit that the people involved are immortal, that would change the equation quite a bit, because fifty years isn’t proportionally that much more than fifty seconds in a life that lasts for billions of years; but assuming the present human lifespan, fifty years is the bulk of a person’s life. What duration of torture qualifies as a literal fate worse than (immediate) death, for a human with a life expectancy of eighty years? I’ll posit that it’s more than five years and less than fifty, but beyond that I wouldn’t care to try to choose.
Let’s step away from outright torture and look at something different: solitary confinement. How long does a person have to be locked in a room against his or her will before it rises to a level that would have a non-zero disutility you could multiply by 3^^^3 to get a higher disutility than that of a single person (with a typical, present-day human lifespan) locked up that way for fifty years? I’m thinking, off the top of my head, that non-zero disutility on that scale would arise somewhere between 12 and 24 hours.
