| Delivery Speed | 30% | 30 | Score based on adherence to estimated timeline (e.g., on-time: 30, minor delay: 20, major delay: 10). |
| Response Time | 20% | 20 | Deduct for slow or unhelpful communication; reward prompt, clear replies. |
| Total Score | 100 | The sum highlights overall seller reliability. | |
