You have not understood me. The examples and theory I mention are mathematical, not the reality with 10 tipsters (or whatever you want to call them). I'm talking about billion tipsters ...
I say that if you could single out the good ones and all the good ones have at least 50% + in the prediction, but in the whole range of odds (because I also have 50% + in matches of 1,40 in the ace) and if they were combined with each other , would bring you a result close to 100%.
The composition of good, tends to excellent, in short and proves.
Now that I say this, this + 50% can be applied to any odds you want. For example, at least you get 100 tipsters who have 60% in matches of 1,40. If they are combined, they may reach percentages that will exceed the "rake" reef and will give a profit.
