I'm not a fan of cut numbers.  I like using T for leading zeros in the serial 
number.  After the first hour or so in the beginning of a contest everyone is 
in the grove.  After serial number 99 I no longer use cut numbers.  Cut numbers 
screw me up in the middle of a contest.

I guess bottom line are we sending/receiving numerical serial numbers or 
alphanumeric combinations?  I think theres a difference.
