OK, posting without reading to the end.
My experience with sequential hydraulics is that there is often a control valve that may, or may not, be adjustable. Basically, it provides resistance to the oil flow so the the first cylinder you want to cycle has to complete its stroke, then pressure will build enough to override the sequencing valve, allowing the next cylinder to cycle. I don't know enough about these systems to know if they even =have= sequencing valves or it's just "free flow" to all cylinders at once and when one set hits the stops, it allows more flow to the remaining cylinders. I'd talk to a =good= hydraulic shop and see if they have a solution. The =simplest= solution would be to literally put separate valves and controls to each slide.
