You are completely wrong so called expert and Bookie. You admit to being a bookie, what a distinguished career you have. Your chart is bogus and so are you.
You'll note I said 'former' bookmaker. That's how I put myself through college many years ago. Nor did I ever use the term 'expert', merely 'professional' -- as in how one makes ones living. Do try to read what has actually been written, rather that what you might prefer to have been written.
As to being 'distinguished', at least bookmakers are honest about what they do (and, btw, it's only in America that 'bookmaker' is a perjorative, not elsewhere); insurance companies, those oh-so-distinguished institutions, are and always have been bookmakers by precise definition.
As to tradesports, I've dealt with them for years with never the tiniest hint of a problem.
Ta-ta.
