Blairo - Nice to hear of your achievement through pumping. I’ve recently added pumping to my routine. I have a cylinder that’s 8” x 1.75”. I pack the width (after 5 minutes or so of pumping) but I have a ways to go length-wise (which is my primary goal). Secondary goal is girth.
I pump about 4 days per week for 30 minutes each time. Pressure is between 3 to 5 hg.
Although this thread isn’t targeted to describing routines, can you briefly summarize how you’ve been pumping for the past 3 years? How many times per week, how long is each session? What pressure? Have you been consistently pumping the entire 3 years? Do you use heat?
