If you are looking at quater lines it has for sure been done.
Not trying to take away your steam as IT IS VERY EFFECTIVE
I believe you would have interest in 2 threads from a guy named "curious"
search for him and then look at his quater line threads him and another fellow posted all sorts of data and what they were doing BROKE THE BOOKS!!
SIMPLE VERSION(s)
first "scrub" the crap teams for both of the following (any team with a win % under .300 for sure(I say for sure because there are still instances to lose but this GREATLY reduces those chances))
1 if a team loses the first half bet them to win the 3rd quarter
(now pay attention to the line for that quarter)
a if it is a Favorite to win that quarter bet the ML (yes juice can get up a little)
b if it is a dog bet the points (juice will be lovely)
NEVER LAY POINTS ON A QUARTER BET
2 Pick a team to win the first quarter (any game)
if they lose that quarter bet them to win second quarter
if they lose that quarter bet them to win the third quarter
if they lose that quarter bet them to win the fourth quarter
IT IS ULTRA RARE FOR TEAMS TO LOSE ALL 4 QUARTERS IN AN NBA GAME
This is NOT my system nor do I claim anything about or for it
Please do your own research using the named site in here sportsdatabase.com (they are a great friend for these)
I think that is it
