I've certainly thought of this before. Weighing heavily against this suggestion is the sheer size of my sample. If what you say is possible, and considering that students are socially promoted, we would have seen some evidence. I mean, nothing stops a student from not getting arithmetic and then going on to be successful with algebra. I started the study looking for such anomalies.
