How long to commit to playlist/stack?

How long do you guys find is best to commit to a playlist or stack of fields?

I have found in the past I would be tempted by new fields and keep changing my playlists every few days. Or get impatient and remove a field before it has time to fully work. I’m ready now to really commit and was hoping to hear from your experience what time frame seems to work best with a stack before switching things up.

with face symmetry I dont need to listen everyday to gain results.
Does anybody has the same experience with different audios?
