I have only owned two of those Canons so far but for the models that I have used, I think it counts up to 6 to 7.
Btw, I haven't recalled Pentax to publish and distribute those camera history charts against what Canon and Nikon have been doing regularly worldwide. The last (and almost the only) one I have seen is only the one borrowed from the AOHC by Pentax Spain, for the Pentax SLR camera from 1952 to 2008.
