From what I understand, If a plane gets away from a ram undamaged, it's because on his computer he didn't touch you, but on yours he did.
Here's an example.
I was in a 1 on 1 with Jensk, him in a 109 and me in an LA.
He had a ton of al on me and I was trying to draw him in real close before forcing the overshoot to get him to burn off some of his E with some hard fast moves to try and get a snap.
First 3 times we did this, nothing, and he was losing E each time and it was getting to the stage where I was almost matching his E.
4th bounce coming in, I leave my evade to the last possible second, watch out of my left forward view as he goes shooting by and all of a sudden, parts are dropping off his plane and smoke is pouring out of his engine.
No noise in my cockpit, no damage to my airframe. On my screen, we came real close but did not touch.
On his screen though, we did touch, so while my computer is sending information to his saying my plane is undamaged, his is saying to mine, his plane is screwed.
The collision model works fine, it's the Internet that is screwed and until connections are faster than lightspeed, it will remain screwed.
