Not sure about the ratio, but if my clutch disengaged that soon I would suspect that it's also not being allowed to fully engage. Which would obviously result in slippage.
Anyway to tweak the mechanical part of the linkage?
Or more importantly at this phase, any way to verify that the linkage is fully releasing when you let up on the pedal? How much play is there between the throwout bearing and the face of the clutch cover when it's released?

Quick question to the OP. Did you install the block plate behind the flywheel. Leaving that out could result in the slave putting pressure on the fingers.
Did you measure from face of block plate to fingers and from bellhousing to face of throw out bearing? This is recomended even in factory applications and there is a spec on allowable clearance but typically you find clearance to big and end up adding shims.
Air in the system would not make the clutch slip but the wrong slave for trans or wrong clutch flywheel could be placing pressure on fingers. On the pedal linkage make sure you have some free play to the upper stop and are not adjusted to push in master.
Also I think you mentioned the first slave failing. Did it leak on the clutch. Did you clean the pressure plate and replace disc when you replaced slave. When you bled did you use a hose to prevent contamination of the disc? Have you checked the new slave to make sure it is not leaking? Have you confirmed linkage is not over extending slave and clutch on release? Some adjustment or use of pedal stop may be required to prevent damage to slave and/or pressure plate.
Last when is it slipping? Hard launch? What are Engine and drivetrain specs? That clutch will not last if used behind a 400+ ft lb beast launching hard at peak torque with 3.50 gears and 35's.
