(27) Knockholt perforating the wrong tapes (e.g. R.0. 95).

(28) Mechanical relays developing 'pips'.

(29) Over emphasis on (necessarily meagre) operational results at the expense of research work.

Suffice it to say that most of these difficulties and troubles were eventually almost entirely eliminated.

EXAMPLE OF MOTOR AND
PSI RUNS SHOWING
COALESCENCE.

     The Χ's have already been set.

     The motor run is BM = ./ ΔD = /

     The S1 (typewriterese for Ψ1) run is the Ψ1 motor run TM = ./ ΔD = /

     It will be seen that the basic motor run was insufficiently powerful to produce the best score at the correct setting; but that the scores on the ψ1 motor run make it obvious that the second highest BM score is at the correct setting.

     One effect of coalescence is that the settings 26, 31, 36 for Ψ1 all score alike.
