In some posts I read about a 15 second delay is not considered as a real time or near real time position display on the map. Question is where is this statement coming from ? If I check the licence of my copy of MP2004 they dont speak of this.
It is only stated that 'near real time' is the transmittion and network delays. So my conclusion is that on or a few seconds more is not 'near real time' anymore. Is this true ?
