Replying to Forward pressure indicator AAAmbition binding?

Hello,

I am wondering if anyone can help me with the setting the forward pressure on the AAAmbition 12 binding. It is fairly easy to adjust the toe height, DINS and BSL (on both the central bar and the worm screw on the the heel piece however I cannot find any indicator if the forward pressure is correct.

Last season I set them up without checking and found that I had several prereleases. There could have been several reasons for this as my boot lugs are worn a bit and I had just come off STH16s in the morning.


If anyone knows how to check the forward pressure on the AAAmbition that would be very helpful.

Many thanks.
