Of course any information can`t be useless. But before spending time for data processing i have to calculate, what will be more profitable - to spent time reading this information or looking for another interesting odds.
And i don`t think that it can increase winning chances, only increase profit - you know yourself what event to bet and here you can choose bookie with the best odd.
Maybe you can use both to have more information and know what you should bet. Yep, we don't know if that can increase the chances of winning,
but we never know for sure if we don't try. But that will depend on how you will use that data because we are free to use it or leave it.
Those who are familiar and can analyze faster than others will be glad to use the other information because that can give them additional information that can help them decide.
This is maths - there is nothing to try here. If the strategy is to analyze bookies odds - this is enough bad strategy. More useful is to check the event information, for sports stakes - who is ill, who played several times a week, who wants promote for example. This will help to choose decision, and the bookies odds mostly not far one from another. With this service we can choose the best odd.
But you are right - this information is free, so everybody can try to use it as he wants.
