Ed, thank you for such a detailed response; it was so good that I printed it out for my further reference. I think that I am starting to get a much better understanding of the properties surrounding the drop screw adjustment, but now I need to try a few things out on all 88 keys. However, the few things that I did try out today seemed provide some amazing insight. I think that I may have been approaching drop regulation from the wrong standpoint. One of the main things that I noticed was that adjusting the drop controlled the duration of the key under resistance of the repetition spring: a lower drop is under this tension for a longer duration. The good part of this, especially with tighter repetition springs, is that the spring can start the return of the key at a much quicker pace, allowing the key return to keep up more quickly with the pianists fingers and convey a more connected feeling in the keys.
