REPLY:

Not so. To get TOO WT WT you would need to have THREE garbled FIGS shift
characters at just the wrong time. Even I am not that unlucky. 

Much more likely you would get only one hit and you would print either TOO 25 25
or 599 WT 25 or 599 25 WT.  To me any one of those is far preferable to
TOOAWTAWT. 

Remember the extra FIGS character (which you don't see) takes only 167
milliseconds to transmit. If your  print is garbled at the other end and he
requests a repeat, that could easily take ten seconds to request and send. In
wasting ten seconds, you have used up the time savings of 72 hyphens. 

Your call.
