Debby,

If you could rewrite the section so that it is clear what the two test
conditions are, that would be great.  I was not sure how to do that, so my
recommendation was based on section 4.4 writing style.

Can you take another look at sections 4.4.1, 4.4.2, and 4.4.3 before you
rewrite the Group Join Delay?  These three sections are different test
conditions.  Throughput is still determined using the same goalposts.
Figure 3, 4, and 5 are the same as Figure 1 with the word 'Tunnel' in
different places.

Any objection to naming the two test conditions?  A descriptive name would
be clearer that a Boolean state.  

Jerry.
