Your performance review average (PRA) is the quality-factor that contributes to your performance score. Your PRA can only be between 3 and 5. This yields performance points that lie anywhere between 0 and 40. Your PRA is determined by the average of your last 15 review scores. If your last 15 reviews are graded 3 on average or anything lower than that, you simply receive no performance score points.

Because of this, you’ll notice that your PRA (which can max. reach 5.0) is not the same as your your performance score points that you receive (which can max. reach 40). Your PRA ranges from 3 to 5, not from 1-5. As such, you cannot multiply the average review score by 8 to get your performance points.

Instead, you have to take your PRA, subtract 3, and multiply it by 20. For example, if your PRA is 4.33, subtracting it by 3 and multiplying by 20 results in your points being 26.6 (and not 34.64).
