Piling Hammer Efficiency for Raking Piles

Can anyone help me in determining the hammer efficiency of a Junttan PM16 piling rig with a 4ton HHK3 hydraulic hammer. I'm trying to determine set calculations for a 1:3 Raking pile.

I'm assuming there will be some loss in efficiency due to the rake.

I normally assume a 65% efficiency for vertical piles.
