Am I bleeding the Clutch slave cylinder correctly?

[Pman1961]

I've looked at videos, etc. and for some reason I don't think something is quite right with my clutch slave cylinder after I have bled the system. By the way...this is the last thing to do prior to setting the car back on the ground and driving it as it has been down over nine months swapping motor and tranny. Okay, the following is how my system was bled:

Slave cylinder is not mount to bellhousing but hanging below.

1) Resevoir is full and cap is installed.
2) I'm under the car holding the slave cylinder level or to where bleed valve is at high point. A clear vinyl tube was placed from the bleed valve to an empty whiskey bottle with brake fluid pretty darn full by now.
3) I open bleeder fitting as my buddy pushes clutch to floor and holds.
4) I then press on the push rod of the slave cylinder as far in as possible then tighten valve while in this position.
5) Did this repeatedly until I felt all air was evacuated.

Situation or problem....After I have tighten the bleed valve in its retracted position and released the push rod, the push rod extends back out a half inch or so. Looking into the slave cylinder without the boot on it appears to have maybe a half inch of travel left. I believe it is supposed to have an inch to an inch and a eigth of travel.

Talking with Brent of B2 and visiting the Tremec site there should be like a .030-.080 space between the face of the throw out bearing and the diaphram so that the throw out bearing does not turn all the time thus reducing bearing life.

My question as I've seen in I believe Moss video on how to bleed a hydraulic clutch. Why does the push rod extend partially after I've closed the valve? Do I still have air or am I doing something incorrectly?

Again, thanks in advance.
