that rocker will be over the nominal ratio so that under LOAD the rocker will have the nominal ratio.
At what load does the rocker go from too much ratio to the “correct” ratio?
You'd be surprised. It does take much. And, once you load the rocker I doesn't change worth more load up to the point of failure.
This is consistent with my findings....I assumed a typo and you meant DOESN'T take much. I don't remember the exact number but it was around 400lbs to full system deflection which was about .027" loss. (difference between checking spring and real spring on a TD shaft system 7/16'' pushrods) typically the TD that I have checked were as described by design with about .02 'extra' ratio. However the shaft system I am speaking of above is LABELED/STAMPED 1.5 and it measures nearer 1.6 unloaded. Because of the placement angle of the adjuster running the longest pushrod possible increases the ratio slightly as well. The paired-rocker system deflection was about the same amount of lift loss as well.
