GPS mOS already over 25 months

On average, the patient pool has been in Regal for at least 25 months now. Shortly the last recruited patient has been already 24 months in. If GPS mOS would be set today, it would be 25 months.

Midsummer 31, a year from now 37 months. Let that sink in. What was the BAT mOS approximately again? Rhetorical question.
