Proof of Usefulness Score
Category Standard

CarMax is a Fortune 500 industry leader with massive verifiable traction, revenue, and utility, firmly placing it in the highest tier of established businesses. However, the submission itself ('SwiftWalker') was of low quality, providing vague claims ('most people have used my product') and lacking technical detail. While the entity's real-world dominance guarantees high scores in Utility, Reach, and Traction (verified via public knowledge), the score is dampened by penalties in Response Quality and Technical Innovation due to the lack of specific evidence provided in the entry form.
