Like the way Hugh is saying , The way I have always judged my hydraulics to see if they are working well enough, is to listen to the engine when loading the system to its set design limit. In other words, right when the hydraulic cylinder reaches its full extension or retraction, you should hear the engine come under a little load as the pressure bypass valve bleeds off. If the engine doesn't sound different under this limit load and you can't hear the pressure increase in the lines when hitting the hydraulic cylinders full extension or retraction, then your not getting full hydraulic power. The way I rate the hydraulic systems for bleed down with the engine off, is if the hydraulic cylinder is holding some weight and doesn't settle much in an hour or so, then it isn't too bad. If it barely settles much in 2 days while holding some weight, then its like new or if even it settles down in 2 days with no weight, I would not worry about it. If it doesn't settle at all in a week while holding some weight, then something is probably bent or binding. I should note here too that if the hydraulics are not under any weight at all such as an empty Fast Hitch, They may not settle do to slight natural stiction inside the hydraulic cylinder and the small amount of natural friction there is in the particular tractors linkage pivot points.
