Hi Delta7210!

People seem to use a lot of different approaches with sleep learning. I prefer to run one sleep track at a time, while others like to run multiples right next to each other. I actually spoke to one customer at a retreat who uses 20 different sleep tracks (!) in one session. He's had phenomenal results, but I find using too many to be counterproductive.

Basically, I would suggest experimenting and journaling your results. That way you can see what is most effective for you and keep tweaking your listening sessions until you find the optimal schedule.

All the best!
