Re: What is the difference between profit on turnover and return on investment?
It seems to me - and this is just my impression from the types of questions that turn up here from time to time - that in Australia and UK the horse race betting industry has a lot of lingo specific to them. I think - again, just an impression, the people giving advice do this to make it seem more complicated than it is.
In this case, from a quick review of a few sites, "turnover" is just their term for the total amount bet over a period of time. So to answer you question, yes.
