This is a great question, topic. 80% of my wagers these days are live. I cannot rely on any 'TV' feed to be my source for when its time to hit the bet button. May too behind and this includes DAZN. I used bet365, willhill feeds to be more accurate and have actually learned some of their timings as to when they take games off the board momentarily (ie on 3rd downs in football). When you learn the timings you can find small advantages to play.
For example, willhill (europe) typically takes about 6 seconds to take a play off the board at a critical play (ie 3rd down at midfield). If I'm looking to make a play, I am locked and loaded on the 2nd down play if the scenario is right...knowing I have that 6 second window.
The number of times I've placed a bet, for example UNDER 43.5 on a 3rd down, then punt, then line instantly moves to 40.5 two plays later....its all about the timing and live plays these days.
I've also grown tired of watching a bunch of games or tickers and would rather just hone in on one or two and try to find these spots...
