  If sequences all are constrained to be exactly 4.00 seconds long then:
  MOE = 1.2 * 32/4 =  9.6 WPM
  MOI = 1.2 * 34/4 =  10.2 WPM
  MOS = 1.2 * 36/4 =  10.8 WPM
  MOH = 1.2 * 38/4 =  11.4 WPM
  MO5 = 1.2 * 40/4 =  12.0 WPM

  I remember reading somewhere that the desired speed was to be between
  8 and 12 WPM.  The above patterns and speeds sound natural since the
  proper CW spacing is preserved.

===============

This scheme has the added benefit of having the transmitters send at
progressively faster speeds as you go from transmitter #1 to #5, providing
another reminder of where you are in the transmitter sequence. I suspect
there is an obvious difference in speed when you go from #5 back to #1.

Whether this scheme simplifies the controller firmware will depend on the
design of your program. Getting away from the fixed intervals actually
simplified the Montreal Controller firmware.
