Decreasing finger movement reduces the number of distinct motions you make without reducing the overall number of distinct motions (though it does reduce overall motion.) I'm not convinced this is as good a proof against RSI as it's often considered, since it only ensures that you will type faster (keeping overall motion more or less static) or type less (which will weaken your muscles due to less use.)
