[me resting at the top of Licklog Mountain (peak #2 of the day)]

From wikipedia:

• Class 1: Hiking.
• Class 2: Simple scrambling, with possible occasional use of the hands.
• Class 3: Scrambling, a rope can be carried but is usually not required.
• Class 4: Simple climbing, with exposure. A rope is often used. Natural protection can be easily found. Falls may well be fatal.
• Class 5: Technical free climbing. Climbing involves rope, belaying, and other protection hardware for safety.

I asked myself on the way home: would I have done this if I had known what I know now?

Yes, yes, absolutely yes.
