 | data.modelGroups[].skipRate | integer | skipRate is a random function whose input value is any integer 0 through 100 to determine when to skip all floor logic, where 0 is always use floor data and 100 is always skip floor data. The use case is for publishers or floor providers to learn bid behavior when floors are applied or skipped. Analytics adapters will have access to model version (if defined) when skipped is true to signal the module is in floors mode. | 0 |
