Given the fact that at some age your bone structure will start declining, and that mewing is a constant fight against gravity. Will there be a age where you look the way you are supposed to do? And what is really the most effective method to bring the whole face up and forwards. I mean the maxilla is one thing but you want to move the whole facial structure upwards not just the maxilla, zygos cheekbones nasal boned and all that aswell.
Exponential theory is helpfull tho, as it claims you'll see results faster and faster.
We dont know exactly the genetic potential of any person. There are some theories set forth by Dr. John Mew but those are not based on any practical studies, just analyzing few skulls from 10,000 years ago.
There are no recorded cases of adult individuals achieving skeletal change, just theories on how to achieve it. There are few good examples of growth corrections in children available, especially twins.
There are 3 studies on monkeys experiencing purposely induced facial rescission.
That's about it.

Seems like lately your threads all ask the same question, ie does this stuff work.
And even if it does work, who is to say that your fully developed bone structure is attractive to your own standards? Some people claim mewing made them look worse. I am not one of them.
