You’ve gotten some good advice here. Yes…growth is the ultimate and final PI, but its unusual to have growth AND decreased EQ.
The problem with things like “jelquing” is how do you convey forces to be used? One guy might do it moderately or gently, while another might be damn near ripping his dick off!!!
I think for many who are slightly over training can “work through it”, just keep going and their conditioning improves and it then is the right amount. Like if you first start jogging, and your legs get sore but in a few days it goes away.
I think for guys like you, where a seemingly small amount of PE is showing negative PIs, the best approach might be to ease up on the force you are using, use a lighter grip and less intense stretch and see if the PIs get better.
The other approach is to PE on alternate days. You might want to try both and see what one is better for you.
Good luck!
