XDJ Sync to Another CDJ Player

After reading all the forums about the XDJ pro link connection, I want to try this. Since I can't connect another CDJ to the pro link and sync all three with the same BPM, are your CDJ's precise enough in timing for me to:

1. Loop a beat on one of your stand-alone CDJ player.

2. Set the BPM the same on the XDJ and loop another beat on side A and mix on side B.

Will the music stay in sync or on BPM until I stop the music?

Will the CDJ stay on beat with the XDJ at the same BPM?
