RAG evaluation metric may be misleading developers

A common metric used to evaluate retrieval-augmented generation (RAG) systems may be misleading, causing developers to overestimate their performance. The metric, which focuses on whether the retrieved context is relevant, fails to account for whether the model actually uses that context to generate its answer. This oversight can lead to a false sense of improvement, as systems might appear better than they are if they retrieve relevant information but fail to incorporate it effectively into their responses.
