I have an mlb sdql with the following

1700 games rated

68% WL ratio

ROI of 5.2%

and if you search by year the ROI and WL ratio are stable

all my sdql is common sense not oddities or strange occurences example line and total and a streak NOT after a tuesday win and a win by 2 points exactly on tuesdays

my question is this is my first true sdql and I am wondering can I use it as predictive?

I mean will it roughly assuming not much changes will it show a 5% roi?

can I expect a game scheduled today to win at a 68%ish rate?

I know I am not clear but I hope you get the point I am trying to make
