I don't think they're the same. Cursed Energy Reinforcement is using Cursed Energy to amplify the physical's body's strength, speed, and durability. Seemingly it's affected by Cursed Energy Quantity, Control, and Output. Cursed Technique Output is... the ouput of a cursed technique, which obviously depends on what the Cursed Technique does: A higher-output Jacob's Ladder will extinguish Techniques more effectively, a higher-output RCT will heal worse damage, and a higher-output attack will deal more damage.
The Hakari scan is useless, it says he ignored Kashimo's CE effect with sheer CE Quantity and Output. It's not saying anything regarding what they mean for AP.
In fact, output is already accepted to mean AP, no? Or is 200% Purple not twice as strong?
