@AnilMakam In medical physics grad school this was taught to us. Radiologist will vary where they are operating on the curve based on patient history and their experience. They adjust where they are FPF/TPF on the curve.
@AmRakaposhi@carlcicahn1 Yes. Many people have "last mile" beater bikes. I've had some campus bikes that I would leave locked up on campus. One got stolen and the other was so bad I left it unlocked for the next owner.
