Some experimentation might help understand what is going on. From this article and what I see on a daily basis it seems that the shared bikes at the CalTrain station get a lot of use and the primary limitation there are the number of available bikes. Perhaps increasing the number of bikes where they are most used would improve the numbers more than just adding stations around the city.
