AI coding benchmarks should report performance, cost, and time distributions

AI coding benchmarks should show distributions, not just one score
The post argues that benchmark results for AI coding tools are much more useful when reported as distributions instead of a single headline number.
It recommends showing:
- performance distribution across many runs
- cost per task distribution
- wall-clock time distribution
The point is that a clean average can hide variance, reliability issues, and real-world cost differences that matter for evaluating coding agents.
