REPLY:

You could not be more wrong. 

The "MTBF", as you put it does indeed stay the same, but for EACH
character, not for all of them. In other words, sending more
characters, each with its own FIGS shift,  increases the chances that
one or more will get through correctly, a simple matter of statistics.
