Tuning How to adjust a Huma-air regulator to its maximum set point, or very close to it?

The instructions to increase a Huma-air regulator set point to its maximum value (in this case regulator for the AEA Challenger with a max set point of 170 bars), specify that you have to move the adjusting screw ten bars above your goal set point and then go back to your desired bars. I want a set point of about 165 bars. How can that be done if you don't have ten bars above that to "play"?
 
Without a pressure gauge on plenum or a test fixture ... your only guessing anyways ?
Maxing out the regs adjustment range is really hard on the sealing disk and o-rings in general. While doable the real limiting issue is the bevel washer stack not being stiff enough and flexing too much to create that high a set point.
I would measure the washers thickness & shop for some slightly heavier bevel washers for what your trying to do.
