I didn't post this with my original research since I did it the next day so here goes.
Nothing new, nothing we didn't expect but if anyone is curious...

PvPDef and Physical def cap out at your opponent's Physical Attack, so in other words a naked gunner with just anticipation on (+3000 PvP def) would drop the damage of an opponent with 3000 Physical Attack to its minimum value. Further increase of either pvp def or physical def would do absolutely nothing. Physical Attack however does not share this cap, so if you have more attack you get more damage, pure linear scaling.
And here are the 2 graphs showing magic damage, again nothing we didn't expect.


And just to confirm what was said in the video about block. 1500 does seem to be the 10% threshold.
