# Effectivity vs Efficiency

TPS: Turn Per Seconds. We can calculate it by counting move counts and dividing them by the total time required to solve the cube. For example, We solve the cube in 60 seconds, with 60 moves. Our TPS= 60 Moves/60 Sec = 1 move(or Turn) per second. Move Count: Total turns required to solve a cube. WCA notation has detailed rules for counting moves. In this article, we would count moves by each 90-degree turn. WCA calls R2, one move. We would consider it Two moves. Why so? Because it would allow us to calculate TPS effectively.  Essentially R = 1 move, R2 = 2 move. Efficiency: Lowest move count used to solve the cube. Our target is to solve the cube in the lowest possible move. WCA event FMC rewards you for your efficiency. Effectivity: Lowest time used to solve the cube. Our target is to solve the cube in lower time possible. Every WCA event except FMC rewards you for your effectiveness.
