I experienced this first hand today.
A France Ligue 1 game...originally they had 60% prediction on the under. Then today they changed it to 54% on under about 6 hours before game time.
I checked it during the game it still showed 54%
After the game it now shows 60% for the over.
Has anyone else experienced this?
I monitor these types of sites and it amazes me the inaccuracy.
Personally, I use a sports service for my predictions and I am very happy...so these scam sites like betstudy and others can just keep their junk. I will keep my professional service delivering 60% wins at odds of 1.9
