### 💡Important Credit Rules

* **Grid-Question Score (GQS):**
  * Each grid item costs 0.05 credits.
  * The total cost for GQS is capped at 2 credits per respondent, regardless of how many items are answered.

* **Time Score (TS):**
  * The maximum cost is 1 credit per respondent, regardless of the number of time-based data points analyzed.

* **Coherence Score (CHS):**
  * Covers up to 100 questions at a base cost of 4 credits per respondent.
  * For each additional question beyond 100, an extra 0.03 credits is charged.

* **Credits are only charged when a respondent’s processing is successfully completed. If processing fails for any reason, no credits are charged.**

* **Credits are applied only to valid and available data points.**

* **No credits are charged for blank or missing responses.**
