Hi Joe,
The longer I've practiced AYP, the more I've realized that self-pacing is the main control lever. It's up to each individual to decide what the right level of practice is. I think of the in-the-moment resistance that can be felt as an indicator more than a safety net. Just like a tachometer on a car, you don't want it to be red-lining for very long. Since writing this post 2 months ago, my practice times have gone down further. I'd guess I'm at about 5 minutes SBP and 10 mins meditation. If I go longer, and engage that resistance, I tend to become irritable, or disinterested in practices for a day or two, or practice only once a day instead of twice. I really think there are seasons/phases/cycles to it. There will be some periods when I can practice a lot, and other periods when I have to slow down.
