Definitely. When your tissues first stretched, it provides the cells to heal and duplicate at that initial point, but just at that initial point. The moment you allowed the penis to retract, you disabled the gap creation after your hard work on the 5x5x3 or 5x5x2. When that happened, there is no more gap to fill. Cells just simply repair and enlarge through assimilation of the damage cells.
We advices the brothers to do post pumping cock ring wearing so that the cells have more time to heal, and to also fill in the larger gaps. The longer you pry the gaps wide open through the long hours of wearing the cock ring, the longer the cells have to duplicate at fill in the gap to encourage the growth. More cramping of new cells into the gaps, more growth.
The healing intervals is the once a day 5x5x3. You only perform the routine once a day, and shorten the amount of time the cells need to heal and fill in the gaps. It will take more 5x5x3 sessions and many more days to break down the cells, expand the gaps, and allow the cells to fill in the gaps. Now, comparing to 5x5x2 twice a day, and wearing the cock ring all day, it gives the cells a chance to work more on filling the gaps.
Think of factory workers filing quotas from a manufacturing location. 5x5x2 is two working shifts, running all day, to make cells to fill the empty warehouse spaces. Same amount of workers but only have one shift. Filling the same empty gaps is not be the same as two shifts.
