Which of the following accurately describes how Formula Indicators are calculated in ServiceNow?

Formula indicators do not perform real-time calculations when a widget is viewed. Instead, their scores are calculated during a scheduled data collection job. The formula uses the already collected and stored scores of other indicators as input. The resulting score for the formula indicator is then pre-calculated and stored in the Performance Analytics scores tables, ensuring fast retrieval and display on dashboards.

A. Real-time calculation on-demand would be highly inefficient for trend analysis and would negatively impact performance.
B. The data is not temporary; formula indicator scores are stored permanently in the scores tables just like other indicator scores.
D. While calculation is often daily, it is determined by the job schedule and is not inherently restricted to a daily frequency.

- ServiceNow Product Documentation, "Create a formula indicator". The documentation states, "The scores for a formula indicator are not collected from your instance data but are calculated from other indicators' scores... Scores for formula indicators are generated during data collection."

- ServiceNow Performance Analytics (PA) Advanced courseware, Module: "Advanced Indicators". This module explains that formula indicators are processed by collection jobs and their scores are stored in the pascores tables for historical analysis.
