English to German Bus/Financial Human Resources sales compensation plans

Of the following compensation structures, which would most effectively encourage you to achieve your peak performance?
 A sales compensation plan with higher accelerators about 100% attainment and decelerators for achievement below 80%
 A sales compensation plan with current fixed accelerators above 100% attainment but decelerators for achievement below 80%
 A sales compensation plan with significantly higher accelerators above 100% but no payout for attainment below 60%
 A sales compensation plan with a linear relationship between attainment and payout (no accelerator and no decelerator)

Mir fällt nur Beschleuniger und Verlangsamer ein. Gibts da was Besseres? (Und denkt ihr auch, dass es bei der ersten Antwort heißen muss "higher accelerators ABOVE 100% attainment"?)
