Only Base Girth Growing?

I havr been using my bathnate x40 as my PE. Over 3 months i gained alot of size using it but i notice now, my gains overall stopped and im gaining alot at my base. When i first started using my pump i was pumping intense and got to 7 7/8” EL, 5 5/8” MEG, 6 BEG over two months. Now I changed my routine and now my midshaft girth went up 1/8” and only gets ~1/8” expansion, while my base went from 6 to 6 3/8” and goes up at least 1/4” in expansion. All of which is without fluid retention of course. After last session for the day I’ll be at 6 MEG and 7 BEG.

Will my midshaft girth catch up?

For more clarification. Since last starting my new routine 6 days ago was when I went from 6” BEG to 6 3/8” BEG.
