then the percentage behind the Max is (6.7%)  Where is that number coming 
from?  Shouldn't it be 53%?  Is there some additional setting I need to 
change or am I just not reading it right?
8 bits = 1 Byte
100Megabits = 12,500,000 Bytes
Adjust MaxBytes accordingly.
You may want the Option "bits" too
