Some of the procedures got to be boring after several attempts, and the carrot on the stick was that you would be able to go on to the next step once you mastered the current one. When a student got the trick, he would be pressured to share it with the others.
The stages to be mastered were:
Once the student was doing full tunings, they were scoped if the time taken was less than 1½ hours. The aim was to get the time down to 1 hour, or less. Graphs were done of the tunings, and it was shown that the faster the tuning, the more accurate.
The graph had a line representing the ideal tuning for the model of piano — a Yamaha U1 — and the cents by which the pitch of each note deviated from this ideal were added up. A total cents deviation of 70 was considered unbeatable, and 150 "lost points" acceptable. Most good tunings were between 80 and 100 cents.
These days electronic tuning devices can calculate an ideal tuning for individual pianos, so in the most recent Conservatorium tuning course a different scoring system was used.
