Math Help, Driveline angle

OK, OK, I admit that all those years I was stuck in the second grade made me less enthusiastic fer spelling and math, but I am purplexed.
In the driveline thread below I stated that driveline vibration can occur at angles greater than 16 degrees. On the link to the Dana engineering page, it states the same info but lists 3 degrees. That seemed wrong to me so I went to the Dana chart of angles and when I place my protractor over their chart, my protractor reads 16 degrees +/- when placed over their chart that is stated to be 3 degrees. What is going on? Why do the angles agree with my 16 degrees on a protractor, but are measured as only 3 degrees on the Dana chart?? I need some mathe genius to explain it to me in itty bitty words. Is there a difference from degrees to percentages or??? I assume that circles are 360 degrees and a 45 degree angle is a 100% slope, so is Dana using that percentage method or??? I re-read the data and they clearly say degrees and not percentage, but....?
