Opinion, yes definitely.
Cut numbers other than T, A or N are too confusing in my  opinion.  Some 
European stations use cuts, and I sure wish they would  not!  I generally 
always have to ask for repeats which is a BIG WASTE OF  TIME!

There's  nothing like a CW serial number contest to get you re-thinking 
about the  use of cut numbers.

For situations where first-time intelligibility is  important, I think 
use of cut numbers probably costs more time than it  saves.  Here's why:

The basic Morse Code 0-9 character set has two  important characteristics 
- each number is five code elements long, and  each one gives you two 
chances to copy correctly or confirm that you have  done so. If you hear 
the first dit of 1, or the last 4 dahs, then you know  what the number 
is.  This is because, with the regularity of  computer-sent CW and the 
presence of "5NN" as a signal to expect the  number to begin at a certain 
time, you can often infer from the length of  the "lost" portion of a 
number what it must have been.  Even if you  only get the two dits of 8, 
depending on when you hear them, you can have  pretty good confidence 
that it was, in fact, 8, and not seven with one  unheard dit.

How much time is saved by sending A instead of 1?   How much time is lost 
by responding to "AGN" or  "NR?"

Opinions?  I bet there are a few out there.
