The engine is from the shoulder instead of from the elbows and spine - can you seriously not see how almost all the punches are launched from the shoulder especially for the smaller guy. The bigger guy is obvious in using his shoulder whenever he throws the right cross overhand. He used a lot of hook style punches which is similar to boxing long hooks though he didnt use any hip rotation. His hooks were not derived from linear force from lateral direction as in biu jee lateral strikes.
The engagement is in and out of range and then sniping boxing style instead of penetrating along the centreline and defeating all obstacles in the path to strike the opponent. The energy is boxing style not wc style. It is quite different from the bare handed chi sau application videos you showed earlier.
No. This is his WC punching action. He doesn't train boxing. You are just confused because he is visually in boxing gloves. There were multiple videos posted earlier of him punching in chi sau/gor sau and you made no comment at all about his punching action until he put gloves on then suddenly it all apparantly looks like 'boxing' to you lol. A noobie error.
The shoulder is involved in arm movements. You will not be able to 'see' all of someone's punching action on a video, you could feel their punches when they hit and the 'internal force' (heavy hits) if they hit with power but they are the one who will only really be able to feel their actions on the inside.
Same with your comments on strategy. You can't have it both ways. The "go in and destroy using punches, neck strikes, elbows, relentless" approach cannot and will not be applied or tested in this setting.
The whole point of any good martial art is it should have a lower gear sporting version. Control the amount of force, engage and disengage if you want step in and out. We have repeatedly said this is sport WC we are developing.
Just like the truth is Karate has sporting and non sport versions.
Kickboxing comes partly from karate. But we never see the famous 'karate chop' ever in MMA or combat sports it's an illegal technique.
When you make a sport version of the martial art you can test it more and develop skills but the strategy changes as well.
You can also spar in many ways, if you want to work on entries and engaging ability then of course you step in and out.
You sound like you haven't trained much or really thought about how training methods can be applied for different purposes.
