Memorial Sloan-Kettering Hospital in New York is likely the foremost cancer center in the world. However, in US rankings, it is at the bottom of hospital rankings because most of their patients die, as one might expect from a tertiary care cancer center. If you looked at the rankings, you would avoid the place as a death trap.
For another example, cardiac surgeons who are willing to take on the most difficult, or oldest, cases have the worst survival ratings. Of course they do. They are the best at what they do so they take on high-risk cases.
That's why No More Numbers makes sense.
