Irrationally optimistic cooling rates

I'm running a 2-part flow model, first for the flow, then feeding those results into the thermal model. 

 

While watching the solver do its thing, I see what I expect as far as a thermal gradient.  Once the solver is done and I load the results, I create a Point Parameter to get the results into Excel.  What I see there is odd.  The temperature falls almost instantly to around half at the first time step, then decreases asymptotically after that.

This behavior is the same at a different initial temperature. 

 

Am I setting up something incorrectly, or misunderstanding something?

 

Thanks and cheers.
