A percentage can be calculated as follows:
    current speed / maximum speed * 100.

This can be written as:
    current speed / (maximum speed/100)

So your target should probably read:
    Target[e1]: 1:public at router / 2400

Reasoning: E1 is 30*64kbps (modify if yours is different) is 1920kbps.
This means a MaxBytes of 1920000 / 8 == 240000
Divide by 100 to get 2400.
