Isn't normal to have delays just by watching a stream? In fact, watching the game does not even change the outcome of the whole match since you are not a player. Only thing you should be worried about are the bets that you are having within these kinds of matches. Watching a non-delayed match would not change your bets and it would not change the outcome so its just weird to offer something like that.
If you really are a gambler, you should know that there are gambling games with LIVE BETTING. Hence yes, there would be a huge impact if the streams would be below 3 second to no delay at all. Maybe try to see the OP's comparison of the video and see how a non delay stream can have an advantage in betting
To the OP, it seems that you do really have a goodhand in here. But the other users pertain to the importance of your livestream onto their betting activities. Yes, they can have less delays with your service offered, but they seemed to have no use of it compared to the present delayed live stream and betting. For them, winning bets just a matter of trust and choice to the player and not to the huge gap of stream delays.
