TOP SECRET Special Fish Report Page 74
But when they want to set psi's on days when motor dots are low, Dragon
gets answers in a truly astounding fashion. For this reason it is kept
busy on low-motor-dottage traffic. It solves an average of 4 or 5 transmissions
a day which might not have been set otherwise. Captain Fried has been forwarding
the weekly Dragon reports, and also sent along the information that Dragon was
modified to permit leaving out any impulse which might be in doubt in the
de-chi. When it operates on only four impulses, the full 10-letter crib
allowed by the board must be used, and the opinion here is that future
Dragons really should make provision for 12-letter cribs, although good
cribs of over 9 letters are hard to find.
