Taken from a post last Friday title "Clutch Slipping". Also, the FSM lists exact figures for pedal travel and adjustment.
Or you could try to adjust it slightly for best performance. Pretty easy to do. Where the pedal pushes the rod into the clutch master cylinder, there is an adjuster. Threads are on the rod. There is a locknut that must be loosened first, but once it is out of the way, it goes like this...
Screwing the rod in towards the pedal (counter clockwise) will let the clutch engage later relative to pedal movement, and unscrewing the rod from the connector at the pedal will let the clutch engage sooner relative to pedal movement. Unless the thing is way off, all you are doing is moving the moment of engagement/disengagement in or out. Adjust it too far in and you will have problems engaging any gears (clutch not fully activated), too far out and you will have slippage with the foot off the clutch.
This is something you can play with, and get right. Sounds like you are pretty close now, and just need a half turn or so on the
clutch engagement rod. Don't forget to tighten the lock nut. I usually loosen the lock nut, turn the rod by hand, and take it for a test spin. If it isn't right, I stop somewhere safe, and adjust it some more. When I'm happy, I take it home and tighten the locknut.
