How TP Practitioners Actually Benchmark: Insights from a Global Survey

CEO of ArmsLength AI

TL;DR - Key Takeaways
- Most experienced practitioners converge on a core toolkit: IQR ranges, 3-year data sets, and weighted average PLIs.
- Percentile methods, loss-maker policies, and sample completeness rules vary substantially across jurisdictions and fact patterns.
- Loss-making comparables are rarely handled by blunt rules; most teams combine guardrails with case-by-case judgment.
- Capital adjustments are important but used surgically, not as a default clean-up step in every study.
- These patterns have direct implications for how we design benchmarking policies, documentation, and tooling.
