I tend to look at KP as a way to test the RPI and what it is producing. While individual RPI's do not matter, conference RPI certainly does as it builds resumes.
It does show some gaps from time to time that show the flaws in the RPI top 50 and conferences in particular.. It can also not be "gamed" like the RPI.
Given that the Big East has 7 teams in the KP top 55, 7 does pass the smell test, but the season worked out as best as it could for them. It was not gaming, but they were lucky there was not another dominant team that could have reduced it to 6.
The mid majors were truly better in 2013 than now, it was not a matter of "gaming" in my view. In 2013, 16 of the top 50 KP teams were not from the P6, including 4 from the MWC . In 2017, only 8 of the top 50 in the KP top 50 are from outside the P5+BE... and 3 of those are from the AAC.
