<P><FONT SIZE=2 FACE="Arial">The RT output of these tests worked =
properly in 1.0.5, although there were other problems reported with the =
tests involving improper assumptions of the next max RT. I think =
this test is still suffering from improper calculations, since the RT of =
this last packet was over the MRT, but this is allowable according to =
RFC 3315. When you reach MRT, you reset RT to MRT + RAND * =
MRT. This could make the value up to .10 * MRT greater than =
MRT.</FONT></P>
