This makes a whole lot of sense. I've seen this situation in mechanisms 
other than piano repetitions, where the spring rate is too high and the 
adjustment is finessed at the limit of travel to try to make the thing 
(almost) work. When a very small adjustment in the spring makes a much 
bigger than it should difference in the reaction, this is a good indication.
