ASCII export data different from simulation output

Hi,

 

I am doing a single omni TX indoor propagation experiment and have setup my prediction plane vertically oriented to the floor. Once the simulation is done I end up having the following files that are dumped

 

After displaying the results in the viewer if I export the power data of the prediction plane separately to a file:

 

 

I see that the ASCII dump (left) and the actual power data file for the TX logged during simulation (right) have discrepancies:

 

<?xml version="1.0" encoding="UTF-8"?>

 

Can someone explain what could be causing the difference? I assumed the problem was with round-off but the third last entry (-27.79 vs -27.95) doesn't make sense.

 

Thanks!
