Efficiency
Efficiency modifiers act as divisors to the stat they modify. For example, 50% increased Reservation Efficiency causes your Reservations to be 67% of their base value, 100% increased Reservation Efficiency causes your Reservations to be 50% of their base value, and so on. Reduced Reservation Efficiency will cause the modified stat to grow larger instead of smaller.
