However the most optimum cleaning methodology in the bore , would be to have the patch contact the whole area across the jag head which translates to the most contact area in the bore when you push the rod through.
Bunching up the patch creating mini pleats across the circumference of the jag seems less than optimal .
I doubt it actually makes a difference, the contact area of the bore is governed by the bore diameter. The front part of the patch is doing the work, the rest is just along for the ride really. If you get too much friction with a single patch thickness there's a chance of punching the jag through the material, that's why I prefer to fold a smaller patch.
