Experienced enough to outduel Sidious. Example with Dessan's TK is hardly relevant because well... it's TK.
Vader was not trying to kill Luke in either encounter, and Caedus is stronger than both him and Lumiya. While anger does give a temporary boost to strength, it also leaves one open up to fatal mistakes, especially when they do not normally fight as such and their power does not come from it. Luke becoming sloppy is why he was hurt, imo. The fact that he is more experienced is the only reason he was able to hurt Caedus as well. Luke has never fought well against anyone on Caedus' level, using anger, while also coming out unscathed.
What's the point of comparing Vader and Caedus? How is it relevant?
Lumiya is indeed not on level with Caedus, however, she uses lightwhip, which required Luke to use second lightsaber to counter until final battle. It is impossible to determine how difficult it was to duel with her comparing to Caedus.
If as you say Luke was sloppy, there is no indication of that in the text whatsoever. All we get is lethal combos from Luke that Caedus barely survives and counters with his own. Both characters show the best of what they can offer.
Luke is at his most effective when he's calm, level headed, and focussed. Not when he's in a bloodlusted rage watching his son getting tortured. Just on the basis that his focus was split between the fight and his son proves his performance was hampered.
The key words you said: calm, level headed, and focused.
Yes, calmness helps, so does anger. Doubts hamper. Luke had no doubts whatsoever. Clear intent to kill. Clear desire to protect his son - a very powerful emotion I must say.
He was definitely level headed and focused. Slash in the kidney elbow in the temple, knee in the chin, knee in the gut, feign attack followed by Force blast, another elbow in the face. Do you really think not level headed and unfocused character would be able to deliver those combos? Throughout entire fight Luke was shown to be thinking and strategical. He was not portrayed as a mindless beast, you imply he was.
