Denver Nuggets @ LA Lakers (IN-GAME)

It's simple. If the first half total falls between 42% to 58% of the full game total, then you have a system play.

The reason for this is that if a team scores 70 points in the 1st half, and the total is 215, the system will give you a "low" prediction since teams in question didn't score at all. As to if both teams score 120 points, and the full game total is 180, the system will give you a "high" scoring play since teams were on fire on the 1st half.
