Like I already stated, it takes more experience to run higher flows through overflows properly, it's not for everyone and it's not necessarily better than lower flow. That article is for beginners, which you would have noticed if you read the title rather than immediately trying to find something to argue with. I would never tell a beginner to use 10x turnover just like I wouldn't tell one to use a herbie overflow either.
