I didn't quote redietz. I wrote what my memory told me. I was off a little. So what?
What you are missing is redietz has said repeatedly that you can't measure EV in sports betting. But there he was on his site claiming he could produce a 10 to 12% earn for clients. He was selling EV to clients. If he truly believed that EV can't be measured, and wanted to be honest/truthful about it, then he would have told them there is no way to measure how much he could make, or not make, for them.
