In the new GT Format, it sure makes sense to me that the being and balance tents would be power stacks, while the body and business tents would be productivity tents. And would allow for due credit within the data for doing both types stacks in a day when working the GT. I've been doing my GTs across Sat & Sun since I like to spend a bit of time on them, and opposed to a weekday where my discover and declare become learning and teaching or posting to social, on the weekends discover and declare are about learning what happened, and predicting what's going to happen, then declaring it into existence through planning using the tools. Accordingly, when I'm doing a tent stack about balance and being, I'm digging deep and thinking more about a conversation with myself and with God and doing the work that would normally be associated with doing a power stack. So I think this change would be appropriate. Could even just put an option in the settings menu to make this an optional configuration if you don't think it's universally applicable.
