What does the urgency score represent?

The urgency score is a metric from 0 to 100. A score of 100 means the group is exactly one person away from reaching the required threshold to unlock the discount.

How is individual savings calculated?

Individual savings is the difference between the `itemBasePriceRmb` and the `groupDiscountPriceRmb` provided to the `calculate_group_economics` tool.

Can I use this to track deal expiration?

Yes, you can use the `calculate_time_to_completion` tool to check if a group deal is still active or has expired.
