I have a set of Veloce shifters, non-QS, and if you look at the way they shift when you have the bike on a stand you can see that they seem to be designed to give that little bump up too far in order to drop back where you want to be. With a little practice while watching I was able to adjust my pressure to get either way; the quick shift or the more positive shift. Try practicing with the bike on a stand and you will likely get the feel that you want.

You mention both; do you have Veloce or Centaur, and QS or older?
