It may mean a couple of things, people will go to the track for a decent plonk, or Pinnacle will replace betfair as the backers preference.
Originally the overseas lads bought whizz bang software which to an extent was supposed to manage the book. It did so, so inefficiently that winners were beating the odds put up for large sums.
The book was not managed, instead they just dropped or severely limited the winners via accounting software which ran independently of the "book".
What they simply need to do is make money like they did before the internet.
Manage the book like Pinnacle do.
Offer odds up to a certain exposure and then drop those odds whilst winding out the odds on those horses at the other end of the market that are nearly 50% below true odds in most cases.
That's not going to happen anytime soon, because they have spent so much money on getting established here, inefficient bookmaking software, but efficient accounting software, so the door is wide open for Pinnacle and Betfair. In fact after commission and Premium Charges, Pinnacle are the best odds you can get. And if you get on at the right time in sports, you regularly get much less than 100% market as a backer
