You are almost there. It will allow a higher weight
if runway length is not a factor (ie, have a really long runway).
Lets say that you are limited by your Vmcg for take-off. You can decrease Vmcg by reducing the TO thrust (less thrust, less rudder needed to fight it). But, in doing so, it will take you more runway length to get off the ground.
Hopefully that makes sense.
