Waypoint density - how close

Hi, new to the forum … with an RTK capable GPS, how close can you set your next and successive waypoints. I ask this because another (GPS Simulator) program required that the wpt be a few meters away in order for it to select and advance to the next wpt.

There is no limit per waypoint, the practical use is only limited by acceptance radius that needs to be smaller than the distance.
