I have tracked this (not a ton I will mind you), but it seems to be profitable by betting OVER the lowest total of the day and betting UNDER the biggest total of the day in a 3 game chase...so you would lose 7 units on 1 series loss...
I have tracked it the 2nd half of this NBA season and NCAA BB season, and it has proven to be profitable...
Any thoughts on if this would work long term?
