According to my measurements:
Big slice: 160 degrees
Middle slice: 115 degrees
Small slice: 85 degrees
Based on Wii U being about 140k, this means:
If Wii U is small slice:
Wii U: about 140k
XBO: about 190k
PS4: about 265k
rounded to nearest 5k
If Wii U is middle slice:
XBO: about 105k
Wii U: about 140k
PS4: about 195k
again rounded to the nearest 5k
That's the best I could do. I measured the angles with a protractor, finding the center with the ruler side of the protractor by measuring the diameter and centering it halfway across.
