Mikrotik NTP client polling interval?

Using 2011 as a WiFi hotspot, set the master MT address as the 2011 NTP client and found that the request comes up every 64 seconds. This is Ok? The main router accesses the external server (pool.ntp.org) much less frequently. ROS 7

The poll interval will increase over time (up to 1024 seconds) when the time has been determined to be stabilized… as usual with NTP.
