Livers is ranked #121 in the composite, which roughly aligns with the average rankings from the 4 services. Some services award 4 stars to more players than other services do. For 247, it appears that the cutoff for 4-stars in the composite is a score of .9200. That score is based off of rankings and ratings from the 4 main sources.
It's obviously not perfect, but it's certainly not "SEVERELY flawed in every sense of the word." What is severely flawed is you picking and choosing with services you think are accurate based on how they rank players that you like/interview.
I haven't seen anyone here fail to make the distinction for Hardy's and Brooks's rankings. People have noted the differing offer lists, however, which is valid.
Also, you are the only person I have see who regularly cites Future150 and Hoopseen. That's like referring to the Bleacher Report Top 25 to validate your favorite team's ranking.
