These ratings are making a mockery of the top 25
LOLOL!!
Those ratings are what's making a mockery of the Top 25? No, it's actually the Top 25 that is making a mockery of the Top 25.
If you give AF about the distinction between a 4.67 and a 4.71, that's your own problem. Those two numbers are averaged from different quantities of individual ratings, most of which are 4.500000 or 5.000000.
The fine line distinctions in the Top 10 and Top 25 lists don't mean anything about course quality. They only mean that you can take mathematics beyond the limits of usefulness and into the realm of pointlessness.
The root cause problem is not that there are vendetta reviews, it's that people care about minute skews in average ratings that can be caused by vendetta reviews. And then people want to go purge vendetta reviews. Then the Top 25 list will be perfect and everyone is happy, right?? No. This thread is just the next step in a death march of futility.
Free your mind.
