Gains after 2 to 3 years become infinitesimal for most practitioners. Some people do not understand that as human beings we are a creation of intelligent design. The Lord in his infinite wisdom decided that muscle growth and expanding cognitive skills we’re more desirable traits for survival than a large penis. With increased muscle strength we can do more work and provide for the protection and well being of our families; increased brain power allows for new technologies and inventions that propel mankind. The Lord thought this was a good thing so He enabled the human form to expand greatly in these areas.
Now, the Lord thought long and hard over the penis; after all, He had already given man His greatest gift and that was woman. He knew that the boner would be His second greatest gift but in His wisdom He also knew that some men would begin to think with their dick instead of their brain, so it was decided that if the penis was given the same capacity to grow as the bicep; soon His creation would be procreating with the livestock than with his woman. It did not take God long to quickly decide that this was bad. He did not want man to become frustrated searching out huge vaginas to accept his enormous penis. He knew that man would turn against Him for this shortcoming but, alas, He was resilient in His decision. But He was not without compassion so He built in a small reserve capacity for potential growth if the owner would stay disciplined to a strong PE program.
You see, your logic is faulty when you attribute potential length gains to mount up linearly to your time invested. Your greatest gains happen in the first 6-10 months (per God’s plan) than they peter out (per God’s plan) and ultimately plateau somewhere down the road. Genetics plays the greatest role and it sounds like you are somewhat gifted in this department, so with a good routine you can expect anywhere from 1-2inches in length and the same for girth. Obviously, there are exceptions but this would be the norm.
