I know. They're pretty obviously terrible.Sure, there are other examples of similar statements as well. However, Gygax didn't use the training rules
A more natural implementation would be XP bonuses rather than training time modifiers.The IDEA of 'how to play well' certainly was there. In the 2e rules this is kind of reformulated into the "give XP for character's aims" rule, which if you think about it is accomplishing a pretty similar aim in a simpler more direct way. The 1e version however is really not that practical, using the ratings as a multiplier to time/cost of training. Its just fraught.
The disadvantage of doing it in the 2nd ed way is that it becomes almost impossible to make sure the class-specific XP systems are balanced against one another.
