Thanks for the reply,

Looking at the signal activity file, if I interpret it correctly, the Toggle % refers to the number of nets that are toggling. If that is true, I have my question answered for the most part.

That said, you bring up a good point that I am not sure about. I think I have a similar problem. I am running simulations on circuits with similar architectures that contain fewer gates and a lower toggle rate (MT/s) yet they consume more power than those with fewer toggles and more gates, which doesn't make sense.
