Worse than it was just last year. Tennis especially. Basketball, baseball a little more also.
Some feeds and leagues are worse than others but it appears there was a concerted effort
and agreement between the content providers and the corporate and state books.
Even the "live" score feeds are in on it. They lag so much as to become unuseable in live betting.
The differential used to be shorter. Not this year.
One major standout is the ATP challenger feed I have been using for so many years. It used to be very close.
Now, it's just like tennis channel.
