(Still, I wonder where that factor three comes from.) Luckily, we hit the other 98.5 % this week. (I’m not that worried by the ~ 15 micromorts of risk I personally was subjected to, given that I spent on the order of 250 microlives for the time that went into this meeting. But my wife, who had been planning our wonderful vacation in Colombia earlier this year, definitely was.) Grüße, Carsten
