A good way to think of those numbers is to think of the number as the volume that the BlackBerry needs to talk in order for the tower to hear it.
If the BlackBerry can talk at a volume of 50, it's easier to understand, and still lots of room to increase the volume so that the tower can hear it.
If you are in fringe coverage and the BlackBerry has to yell at a volume of 100, that's the loudest it can go, so if the tower can't quite hear it, it can't yell any louder, so it has to retry at the same volume and hope the cell tower can hear it this time.
Now consider the impact on battery life. If the BlackBerry only has to yell at half volume, it's not pushing as much power out, therefore the battery life is better. If it has to yell constantly as loud as it can, then it's going to be using more power and battery life will suffer.
Does this help?
