Balance and Load Balance in bfgminer

[Mach]

Trying to understand the balance and load balance pool strategies in bfgminer.  Is there anywhere I can read a more detailed explanation of these strategies than what's given in the README file?  I've googled but have come up short.  Are they meant to rotate between pools one at a time with all available resources, or should they be mining all pools simultaneously and sharing available hashing power?  From what I can tell, they still just mine one pool at a time and then rotate to the next.  But if that is the case, what is the difference between balance and round robin?

In fact you read the "readme" file to know what you want to know in either case try to contact the Bfgminer support.
