This is what I know after reading GCMS notes. This may /may not apply to LVO.
for CIC-O medicals, they look at it exactly 60 days from the day they issue request for medicals. If you do next day or 3 weeks after, it does not matter, they will review & update system 2 months from that date.
They will say 45 days as it takes 15 days from medicals done to send report by doc & processed by staff in CIC. Ef CIC staff does not see medicals on 60th day in the system, they will issue another letter to complete it.
