Suppose you want to make a level with a bonus warp that leads to a seeker powerup and full health. This bonus warp requires a lot of coins and therefore takes a while to access. The problem comes in when a skilled player successfully attains this bonus. He's skilled enough that he can do without the powerup, and with it he can prevent others from getting it and can create a lead for himself as well.

Without limiting or excluding the powerup and carrot, how can a system be made so that this bonus benefits the weaker players more than the skilled? If someone posts a solution, try to find another one.
