Adaptive LLM Judge Tuning Shows Universal Gains Over Fixed Parameters in Early Sims

The developer reconsiders the previous rule of thumb of 0.4 IRR (Information Retrieval Rate), which was developed under a PPI implementation with a fixed shrinkage parameter for λ.
He proposes an adaptive solution called "power tuning tuning," where the target shrinkage for λ dynamically depends on how aligned the judge appears to be. Early simulations indicate that this approach is almost universally better than either fixed alternative.
