I looked at the first one for NBA. I cannot run a query that gets all wins in a row up to N wins, I have to run the queries one at a time. This is over the last 5 years. I only did 6, 7, and 8 wins in a row. These are SU results, ATS results were pretty much even number of wins and losses.
If you bet against win streaks over 5 games you are going to get killed.
Here is win streak = 6
1341-742 Average line is -210
win streak = 7
889-446 Average line is -210
win streak = 8
608-276 Average line is -240
