i'd like to hear some more on this. i'm of the opinion that drills can be quite helpfulQuote:
There is an interesting phenomena associated with approximations, typically in MA referred to as "drills" and when presented it will run counter-intuitive. However, the "truth" regarding drills is in fact the truth. Namely, drills tend to be far more counter-productive than assistive in nature. I'll provide the rationale for this being the case at some future point in time.
