I get into these modes where it seems to buffer my twists, so I see the area I want to stop at, but the list keeps on scrolling by me!

You must be running beta 11. This problem seems (to me) to have been significantly reduced in beta 13.

Also, the other comment about twisting it "fast, but not too fast" is accurate. If you twist it too fast, it kind of mis-reads the clicks and gets throttled.

Upgrade to beta 13 and give it another try. I can quite literally get to "S" or "T" in just a few twists.
