doesn’t seem to matter that much what you do while you run it. That’s why Sub Club has never given explicit, specific instructions for this point.
As long as you keep it safe though, you’re free to do your own experiments and figure out what works best for you.
If you want to develop this topic further, my recommendation would be to quote specifics (ideally, these quotes would be from the formal published listening guidelines, support instructions, or from actual posts you have read from Saint or Fire). Otherwise, in a forum with so many of us actively theorizing, it’s very easy to contribute to misunderstandings.
