Your overall time isn't impacted by how fast you can go, but is normally dictated by how long you spend at lower speeds. Since I'm on a MUP partially and stretches of lower speed are unavoidable, this naturally boxes me in to a certain range. So in reality, plus or minus one or two mph within the range depends almost completely on how many times I slow down for pedestrians, slow cyclists etc. So I think that my faster commute was just due to a little relaxing of judgment from feeling under the weather. Mea culpa. One more thing to adjust for, that I hadn't really considered before.
I've noticed the same thing on my commute ... I think that's largely a "metropolitan" issue though
