but once again accuracy differences even with a 1-2 min old RTCM correction would still be very minimal.


Do consider: Effects of RTK correction data age on accuracy

RTK-capable GNSS receivers will maintain the RTK fix for a limited amount of time after the RTK correction data stream stops. The time usually ranges from 10 to 60 seconds. For receivers that only go to 10 seconds, this can potentially be an issue when using the Internet to transport the correction data due to unexpected network congestion on the Internet or wireless carrier.

On a different note, "Professionally, surveyors avoid using older than 10 seconds, this ensures the reliability of the fix."
