First congratulations on the gains you have made, as others have said they are similar to my own. I gained my first 2 inches in length in the first 6 months with a gain of 1/2" in girth. These were partially newbie gains but predominately new exercises I invented and implemented. After this it took me another 10 years to add the rest. This is very normal, as the penis becomes larger it increases slower but it will never stop increasing, it just becomes a situation of adding enough intensity to make a bigger cock grow. As far as going into Phase 2, I suggest forgoing Phase 2 and going with
SRT, it is just a better routine, you will make quicker and safer gains while allowing your penis to heal in the best ways.
Your goals could be made through newbie gains if they be modest enough but if going for a 11 inch penis, plan on digging in for a decade.
