velocity detect
 

I have a plugin that detect velocity when player is jumping. So I want to detecting Player's first jumping velocity and second jumping velocity and third,....
I want to detect if player's first jumping velocity is equal to second or third jumping velocity the player is punish.
Example First jump : 250.000
Second jump : 250.000
In this example this player should be punish. And should be a cvar that I will setting detecting which jump number. When cvar is 5, first jumping 250,second 250, third 250 , fourth 250, fifth 250 and the player will punish. Can you edit this plugin as that style?
