The stream doesn't have a big advantage compared to the Polish bookie that you had open on the right. It is certainly not 4-6 seconds faster than the entries of the bookie.
Is the delay always the same, no matter what match is on? To run the streams, do you need to login to a site, platform that holds all streams for the tournament or is it the same link for all matches.
What about other tables and courts? A tennis tournament is usually played on 2+ courts. Are their streams for each court? Any advanced features like modifying the buffer length/speed?
Can you make a video of a tennis match running alongside your stream where the bet365 match center shows the entries of the points?
5 seconds is enough to stake a bet on a good not limited account. I.e on. B365 it's depends on tournament, but markets such as: "Race to 3 points" have 1s of buffer to stake before the game.
Let's focus on that only one tournament I have in offer. There is match after match only on one Table.
You are getting the link for the tournament stream with modifier of video buffering.
