While they are active, it says that elusive(or power) running rolls are guaranteed to be 20% of the max.

Can someone explain what it actually means?

Does it mean if the elusive running is potentially maxed at 100, it is guaranteed to be 20 if the Juke skill applies? If true, then what if you already have elusive running higher than 20? Or am I getting this totally wrong?

Basically, When the dice get rolled to add to your skill to determine an outcome, instead of your dice roll adding 1-100 to your skill, it will now add 20-100 instead. The worst possible outcomes are shaved off.
