Well, this is for the 3.2 but may work on your hybrid:
Before you adjust anthing, remove, clean and lube the shaft of the helper arm and clutch arm shaft that comes out of the trans. All this adjustment and a binding clutch is very frustrating. Ask me how I know.
I will just focus on your question of adjusting the clutch:
A helper would really be asdvised to press the clutch pedal as you take your readings and make final adjustments.
I assume you have the car jack uped already and safely with jacks and chock.
OK, with the cluth pedal untouched, get your first reading. It is measured from where the cable disappears into the end loop to the the tip of the adjustment barrel. Note that reading.
Ask your helper to press the clutch and take the reading again from the same points.
Now do the math. the difference must be 25.0 MM (+/- .5MM). That's it.
Like you said if she ran perfectly couple of years ago. Why worry about it, Enjoy your Baby
BTW, one thing I have to mention is it appears from your pic the cable looks like it is maxed out i.e. Stretched. If you can not get any further then where you are at in the above pic, you may need a new cable or see if you can get a shorter one. My 2 cents. The cable has to work triple duty with it's current set up from what I can tell.
