Yes, it’s possible. Cutting down on the number of loops is the most effective way to overcome stonewalling. You can’t really brute force your way past it, as the subconscious will simply stonewall even harder.
The second (and more difficult strategy) is suppressing the lust for results. Constantly looking for results can actually short circuit the process. You just need to run the sub and take action and let the alchemical process occur.
Also, a lot of times when people are saying that “the results dropped,” they’re actually referring to the loss of ACUTE results. When you first run a sub, you’ll immediately start seeing results because the scripting is new and novel to your subconscious. After a couple of weeks, your subconscious becomes accustomed to the new reality (to an extent) and it isn’t so “novel” anymore. This is when the deep work occurs, where you have to be very self-aware of your past patterns and habits. That way, you can really gauge if you’re truly stonewalling, or just becoming used to the new reality.
