Bill is right here. I stay corrected. You adjust according to the speeds achieved.
However, this requires an accurate airspeed system installation. I'd suggest to begin with a 13 degree elevator up and go from there.

They want it adjusted for power off minimum airspeed of 60 mph. If flight testing reveals a speed of less than 60 mph, moving the spring into the next hole that would reduce the effective length raises that speed. They deem it OK to be a bit high, but not less than 60 mph. So you will feel the spring resisting the yoke well before the stall at some speed above stall speed.
