I think some people do what is suggested in the first post of this thread, they gain for a little bit and then start pushing the ruler in under the pubic bone when their newbie gains stop. There is a tremendous capacity for people to want to see themselves proceeding towards a larger dick and switching from standing up to sitting down or pushing in further or measuring from the side gives a lift to the ruler measurement which means they don’t have to think about and correct their routine.
No doubt that what you say is true, mem. Using little tricks to fool ourselves.
That said, all we can do is the best we can do, and 100% for sure, having “before pics” is much better than not having them, in my opinion. Of almost any quality, though we should strive to be consistent, at least.
That aside, depending upon the size gain, moreso than the quality of the pics (within reason), some gains seem irrefutable. The best example of this, in my opinion, is in 2-inch Growth Comparative Pictures. Although there is no ruler present, bennett8’s gains are obvious.
