If the friction is too high the derailleur will not move to the proper position without "coaxing." Sometimes you can check for that problem by "plucking the exposed cable at the down tube to see if the derailleur moves further.
Trim - yes, one click would be the trim position for the small cogs with the small chainwheel, and is also available when going back down for the larger cogs and the middle chainwheel.
Thanks for the response!
I checked all the exposed cables and lubed everything I can see (barrel adjusters, under bb, where it attaches to fd, and ****ers) to no avail. There's no fraying (aside from the tip because I lost the cable cap) or stickiness anywhere.
I just rechecked the trim on my shifters, going up, it has 4 clicks - trim to middle to trim to large and then on the way down, it's just 2 clicks - middle to small.
