Mr. Joe Lewins:

With regard to turnover, the betting industry is a churn business. If a person goes to a betting shop with €10 and is lucky enough to back a winner at 7/1, that person has €80 in his or her pocket. That €80 could play out for the rest of the day. Turnover is a somewhat fictitious figure as the original bet might be €10 but it could lead to €90 or €100 in bets. It would be difficult to use turnover as a result.
