1) Conventional rim is just an easy benchmark.
2) My point was that the difference is pretty small to start around .2mph to .4mph. If you already have a wheel more aero than a conventional box rim , its going to be smaller.
3) I believe, The OP has Soul 2.0 wheels with a rim height of 25mm, so those are not going to be a whole lot more aero than a conventional rim.
