Yes, by changing the duration this is a 'new test' to the database. 
Eventually the old data set will be moved to 'non-active' at the bottom 
of the screen.  We are aiming to add more information to display to make 
this more evident in the next release.

The other direction is not succeeding.  There may be a firewall in the 
way, there could be NTP issues on either end.  Try doing a manual BWCTL 
test (e.g. bwctl -c HOSTNAME and bwctl -S HOSTNAME) from the terminal to 
get a better idea of what the tool is reporting.

No, this is an 'expert only' area and we would not recommend manually 
adding or deleting things.

Thanks;
