Sgt. J. Levine at Arlington has gone into the accurate scoring
of rectangles as far as anyone here, and all data compiled here on accurate
scoring are already in Arlington's hands. Here they do not find accurate
scoring in converging to be worthwhile on a production basis.
After the Delta-X1 & Delta-X2 patterns are deemed to be significant(and
therefore
the rectangle is called "significant,") the rectangle and the patterns for
Delta-X1 & Delta-X2 are sent to the Colossus operator, together with the Z tape.
The Colossus operator plugs the Delta-X1 & Delta-X2 patterns on the machine.
Then he performs wheel-breaking runs.
For instance, using the Delta-X1 pattern only, as against a Delta-X2
pattern of all dots, he makes a count of resultant Delta-D 1p2 = . positions.
This is called the "Normal Score" ("NM"?) Then the last dot of the
Delta-X2 pattern is changed to a cross, and another count is made on 1p2.
positions. The last position of Delta-X2 is changed back to a dot and the
second to last position of Delta-X2 pattern is changed to a cross, and a count
made on 1p2. position. This is done for a cross in every position of Delta-X2.
