The latest iteration of the code (I fixed the bug you pointed out, and another one that I spotted myself) reports 1 death per 0.66 years, which is close to 2 per year. The remaining difference, as you said, could be due to the mortality rate in my model not accelerating fast enough past 100 years old. I'll have a play and let you know.
