This is a personal preference thing. I use adjusting the +/- I play if losing or tied. I use the adjust tempo if losing only.
And as an example: My team was down more than 15 at half playing slowdown. At the half, the system adjusted to uptempo to give my guys more possessions to make up the deficit.
For +/- if I’m -1 and the opponent is hitting 3’s, and I’m losing or tied, the system will adjust 2 places to +1.
