Not much science on how the weight is picked and results surely vary by setup more than just the weight.

REWARDS is a program which adds weight to drivers who achieve a finish in the top-three, maxing out over the season at five percent of the base minimum weight of the car. REWARDS weight is removed if the car finishes out of the top-four. The purpose of the program is to help provide the closest on-track competition between a diverse variety of cars.
