WAIT!! Don't change that assumption!  I did want the "super-precise" 
calculation.  I just get frustrated with myself when I don't realize 
the first order answers until someone brings it to my attention.  An 
answer that is close is OK to start with but I really do value your
backing up my work your calculations and tutorials on how to arrive 
at them.  Thanks for your help!
