You might be right but they are clearly talking about books in general in that video and not just Cantor. So if that's the exception then they are misleading.
Ok here goes.....he can be a bit long winded but great information from an insider who has been on both the book side as well as the handicapping side. And Go.......
First, this is a rather complicated subject. My views have shifted a bit on this but overall remains pretty consistent.
First, there is no question that the books have some of the best algorithms in setting lines. They have the best working for them, at least on the creating the line end.
However, sophisticated sports bettors have caught up and in some instances have surpassed the books in coming up with an accurate line.
My thought is that this has occurred for a number of different reasons. The first is the ingenuity of some of the professional sports bettors and their expertise in programming. They incorporate variables into their techniques that typically you do not see books even attempt to quantify into theirs.
That is why you see reverse line moves in many instances add value to whatever handicapping technique you are using. These reverse line moves reflect in part what the best of the best handicappers are doing.They tend to move massive amounts of money into the system which is reflected sometimes in a low % public side’s line moving opposite of the % action.
But saying that the books tend to be different in how they evaluate what type of action they wish to get. Some move their lines substantially with the action while others barely move and take the heat.
As an aside, this is a good thing for a sports bettor as long as you have access to both types of books. You get to pick which line you want to bet, a sharp line or a public line. This is no small thing! It can add many units a year taking advantage of this.
So to answer your question it all depends on the book. And that depends on who is running the book and their concept of risk along with their volume of wagers.
A small book does not have the luxury of relying solely on a algorithm while books like Cantor Gaming to a degree can.
My opinion is you are both correct on this one. Even in this day and age, there is still a substantial difference between how books handle their business.
My comments are given as a general proposition. Each sport has different considerations for the books. The extreme being the NFL where the public still has a massive footprint in the betting. But even that has shifted a bit over the last 5 years.
