It's the cap score. A perennial allstar, for example, has a hard cap of 22.00, if I'm not mistaken. If a guard's cap score is 15.63, and an OD pop is currently 0.3, their new cap score would be 15.93, assuming the pop in OD.
Here are the cap scores for potential, IIRC:
Star: 18-20
Allstar: 20-22
Perennial Allstar: 22-24
Superstar: 24-26
MVP: 26-28
HOF: 28-30
ATG: 30+
