driveshaft angles

This shows the problems when the two angles are not the same, you get vibrations. The joint speeds up and down going the full revolution on an angle so if one joint is changing speed and the other is not quite the same angle it’s a pull and push affair, vibration. Over angled joints absorb HP like crazy.
That's true, it does. What it does not show however, is how the suspension loads and changes the u joint working angles. Without that added into the equation, you cannot set the angle correctly. Every bit of this is covered in the MP chassis and suspension manual. I just don't get why some people (not you) want to say their methods are incorrect, because they are not. They're spot on.
