Query on RTO Compliance Duration at Cognizant

I’m currently awaiting my promotion at Cognizant ( completed 24 months, joined 2023 sep 1st ) and wanted to clarify something regarding RTO compliance.

Does anyone know from how many months Cognizant considers RTO compliance for promotion eligibility? Is it based on the last 6 months or just the recent 4 months?

Would really appreciate insights from those who’ve gone through the process or have clarity on this.
