This is magical numbers thinking by shape rotators. How does one qualify the new candidate being better than 50% of current team. Better than 50% at what? Every role has many dimensions, and most members of the team have a mixed set of strengths. You form a cohesive package if you hire complementary people and get 2+2=5 type of output. The idea that everyone can be treated as an interchangeable cog and objectively, quantitatively ranked is pure silliness.
