  Key Findings

  1. ISONGraph wins on both efficiency AND accuracy - 92% correct with fewest tokens
  2. ISON/ISONGraph excel at multi-hop queries - LLM can follow relationships easily
  3. Acc/1K metric shows ISONGraph provides 3.5x more value per token than JSON
  4. Graph-specific format helps LLM understand relationships better than flat JSON
