Getting the pleat right at the join.

[plaid preacher]

Glad you found a solution. The reality is that because the join is deep inside the pleat it has no bearing on the sewing of the fell. If you look at Steve's photo, the material gets cut away. All you need to do is take the edge of the last pleat and line it up with the fabric for the next pleat ...and sew.

Good luck with the rest!
