My short term goal is 3 full lifts per hand during the 60 - second period. (dieselcrew.com)
The lift of the valve is a function of the quantity of oil addressed to the actuator, ranging from full lift to complete valve closure. (greencarcongress.com)
I found that without resistance I can lift 175 on bench 4 to 5 times (all the weight plates I have unfortunately) but only 140 with the resistance (it equaled out to about 190 at full lift) (trainingscience.net)
