FDS and MTR values

Following the FDS users guide and other various publications I have been trying to get up to speed with the Measure of Turbulence Resolution, Wavelet Errors and other exciting reading. I have the data from a subgrid KE device, and the U V W velocity device in the same location with a calculated TKE baed on a 10s rolling average. When I calculate the MTR value for this point, it seems more like a random number generator despite a fairly fine mesh and a datapoint away from the fire. Any experts on this?
