I mean get why you’d want something physical in results listed. But honestly you just run it, see the results internal and external change yourself. Be it quick or slow, you get there. You state for example this sub so and so got x amount of increase in length or girth in so so amount of time. Then person B in same amount of time under different limiting beliefs or starting points will be like why didn’t my thing grow in the same way and speed.
Then further enhance their limitations on them not being able to increase physically in whichever way they wish to. Most of here have experienced these limitations or breakthroughs we encounter when running subliminals. Most of our gains are in realizing that we do not have limitations but the ones we or others place on us.
Short story to this is that each of us are different and have different starting points and having this kind of data would be counter productive. Like I don’t need to know the data behind why my phone works and or my vehicle, it just does.
