My method:

Pull the back wheel back as far as I can with chain connected to cog and crank, wheel being held back between legs, tighten bolts evenly and ensure there is no rubbing.

Am I missing something or is this the best way to got a decent amount of chain tension on a fixed gear?

I did this today (because I installed new tires) and chain tension seems good but I am wondering if there is a tried and true method to this madness.
