Is there a lot of loss though, with normal mode, or any at all?  The
way I read the documentation, it seemed to me warning that there might
be some, and since my scan are more worried about accuracy vs speed,
I thought I had to use "polite", but I also have to deal with about 150
Class B's that need to be scanned.

Please let me know what you think.  and thank you

Polite mode will slow you down *a lot*.  I don't really have
recommendations for # of concurrent nmaps, although one or two dozen
is probably safe in this particular case.
