I've just had a new clutch fitted to my Z. The biting point happens as soon as i take the pressure off and after the clutch pedal has traveled 2 inches the clutch is full out. The pedal also sticks at this point and I have to nudge it with my foot to allow it to return. There also seems to be a lot of slack as I push down the 1st 80% of the depression.
Hope this makes sense
