I have it:
rd1: Kampmann - clear winner
rd2: Diego - close. i think Kampmann may have landed more punches, but they were too soft and Diefo landed the biiger punches and rocked Kampmann
rd3: very close to call - pretty similar to the second rd: Diego threw more punches, but he missed a lot.
Kampmann landed some punches, but again, he was countering Diego's attacks and the punches didn't have too much stregth behinf them, regardless of how Diego's face looked after the fight. I think that damage was caused in the first and just agravated a bit in the 2nd and 3rd.
In the 3rd Diego left the impression of the aggressor, chasing Kampmann in the ring, he controlled the octagon, got once TD.
Plus Kampmann didn't do anything after he realised his arm is broken - last 60-70 seconds i believe.
I would give a very very close decision in the 3rd rd for Diego.
Thus a 29-28 decision victory in the end.
I think Diego's aggressiveness and him constantly moving forward in the 2nd and 3rd won him the fight in the end.
But no way is this decision in the same cathegory with Phan-Garcia or Fukuda-Ring!!!
