Hi Neta,
Your questions and statements are good and valid.
The common response here is 'Your mileage may vary'.
So everything that you pondered is correct.
If you have the boob gene, then growth will be easier. if you have extra fat then you can work with that too. And most important is your hormones, too much T or E will cause some issues.
Generally a 2 cup growth is the max but their are exceptions to every rule, but to grow over 2 cups requires a lot of all the good stuff happening and constant attention to the process.
And as far as permanent growth grows. Its permanent but your growth needs maintenance. Like everything in your body, if you ignore it, it will not work well when you need it.
