Anatomically, you might not even have the cuts or muscle separation in the lower Abs. Because at 7.6% you would see them. I got down to 7% and I had a 7 pack, that last one was just smooth no separation at all! Not everyone is going to have perfectly squared Abs.
So I think a strong 4 pack with the next 2 peaking out is the best you're gonna get. But you've done GREAT to get that!
Shift your focus now on building up the other muscles and maintain the Abs you got.
My past schedule i was doing abs and aerobic 3 times per weeks time on off days, my present schedule I am doing abs and aerobic once per weeks time nowadays actually, so do not miss morning meal it may be more important than you think.....
