Is the effect significantly reduced if I use 2 fields at the same time, from different devices or it is only slightly or somehow reduced or perhaps it’s not reduced, depending on the individual?
If I only listen (to) one field at a time, it takes forever…
But, I think Quality beats Quantity, yet not if the effect is not reduced or just slightly or somehow reduced (if I use two fields simultaneously).
What is your view?
Is there a consensus?
