Not really Geoff, if the plate is radiused on the downward side it's no problems.Without the radiused stop plate the petal is more flexible.Like the ruler over the desk type thing ;)

That's just it, the plate looks square edged to me.

Geoff I know what you are saying and I agree the sharp corner should be the other way around but this is how Boyesen recommend you install them.

Apparently smoothing the leading edges on the petals with 800 grit paper will stop the edges feathering and will last longer.

Smoothing the ends helps but oil is what prevents the ends fraying. It acts as a cushion between the petal and cage.
