Again, thanks for keeping this up, Pooga... albeit belatedly. :)

I think it's a fairly easy explanation. We are only seeing growth in the "new" markets. I suspect that in the lead cities, such as Saskatoon, that if you analyzed further, you'd really only see established trackers hitting notes. This "saturation" is typical of diffusion theory (check it out in any good human geography text :) ). Thunder Bay is easy to explain -- ever since Honeybabe was finally abducted by aliens late last year, the field that she saturated isn't going to generate any more hits. Really good stuff here... maybe I'll present another paper on it.... :)
