It looks like a pretty detailed study but it wouldn't be the first time I've seen such a detailed study that gets it wrong. And I don't know if they are focusing on the right thing, because what is clear is that instant betting is what people are hooked on much more than it was 30 years ago. Nowadays you can bet on practically anything, at any time of the day from your mobile phone, that's what gets people hooked. Not like 30 years ago when you had to physically go to a place to bet.
