XLO burn in disc:

Have anyone noticed any benefits to using the disc particularly tracks 7, 8, & 9. I've recently upgraded a whole sleuth of components and cables and been playing the disc a couple of times so I can't isolate whether the tracks provide any real benefits. Also, for those familiar, how long should you run the tracks for to fully utilize it? My thanks in advance.
The burn-in track should be played for at least several hours but better to play for up to three days. Play must be continuous. Track 3 is outstanding for speaker placement.
The demagnetizing tracks work very well. So does the burn-in track (#8). I leave it playing overnight and it works well.
How about the PAD disk (2 versions)?
