Mancini/HS 1.6 rocker not giving me the lift expected

Looks like the Hughes rockers in post #20 may have labeled a 1.5 ratio rocker as a 1.6 ratio rocker. You can see the rocker on the left has the adjuster more forward than the adjuster on the right. To get the 1.6 ratio, the adjuster is moved closer to the center of the shaft.

Either way, quality control from their rocker supplier or parts marking team if marked by Hughes themselves is lacking.
