Total Reward as Sum of Segment-Based Scores

Examples of Constant Segment-Based Reward Functions

A team is developing a reward model to score segments of text generated by a language model. The standard approach calculates a segment's score using the initial prompt, the complete generated output, and the specific segment being evaluated. To improve efficiency, a developer suggests modifying the process to calculate the score using only the initial prompt and the specific segment, omitting the rest of the generated output. What is the most significant analytical flaw in this modified approach?
