Twenty Nine Dufferin / by Simmon Li

So, I was on the TTC today (oh my god!) and I always see the 29 Dufferin bus come in pairs or even triplets. I know they recently increased service to this route, but it doesn't really seem like they did. I mean, yea I stand there for 20min, then 3 buses going the same direction come within 2min of each other. Maybe I'm missing something here, but wouldn't it make more sense if you spread the buses out so they come more often? What gives TTC? I know Dufferin near where I live (near Yorkdale mall) had construction going on, so that's okay. But that's done now, and I still see it happening on a regular basis. I don't know if it happens on other routes as often as it does on Dufferin, but I've seen it happen on a few of their busier ones. It sort of baffles my mind, I really don't get it. They claim that now wait is maximum 30min, and their right; but honestly, why do the buses come all at once? Is it just scheduling problems? Someone please explain this phenomenon to me.
