I think the whole 3 minute thing is very much sub dependent, and based on the density of the script itself. I remember seeing different numbers of minutes quoted in different places during the earlier discussion including 5 and 7 minutes to get the whole script.
My personal preference tends to shift depending on what subs I’m running, the frequency, and the purpose. For example if I’m taking a new sub for a test drive, more often than not, I’ll run a full loop of it up front rather than ramping up to the 15 minutes, to get a better appreciation for the “feel” of the sub. Some subs I tend to run for almost half loops or more before moving on to the next one, while others especially when stacking I’ll go as low as a minute 30, but usually 3min or 3 min 30.
The fact that when you went beyond 3 minutes you had massive recon suggests that 3 mins didn’t have the whole script, only enough to accomplish what you wanted it to. I remember @William had similar issues in the earlier days with the sub 1 minute microlooping of WB, and mere seconds could make a huge difference in the recon levels. Recon not occurring below a threshold suggests that above that threshold you’re being exposed to new content that is not yet aligned with your personal zero point.
I think the key here is not to stop dead as soon as an increase creates recon, but to push your limits within the bounds of reason and try to get over that recon hump gradually, and look closely at the nature of the recon so you have a better chance at addressing it.
Edit: to make my point clearer, the advice to ramp up gradually is there, in my opinion, so that people can identify and manage recon in an individualised manner, and choose when to push past it while still retaining the benefits of the earlier script until that time. This is becoming less of an issue with the newer technology, but the goal as far as I understand it would be to be able to reach the reception of the full script / file without recon eventually, even if you choose to later use the microloops as a way of reminding yourself of the whole script once those tracks have been fully laid down in the neural landscape.
Feel free to tell me I’m wrong or whatever, this is just my perspective after years of using the subs.
