Calculated HFR metric for subs appears to differ significantly in v1.10 001 compared to the last v1.9 beta build

Example N.I.N.A. .sub and screen captures below

N.B. A Bhatinov mask sanity check shows the stars in the subs to be at focus

HFR value calculated in N.I.N.A. v1.10 001:

HFR value calculated externally:

Example sub here

The calculated HFR value is consistent and so does not affect the imaging session in any way

The issue has been tracked down to a ushort overflow, and a PR has been submitted. Paradoxically that may actually have helped with AF as it was increasing HFR of out of focus stars more than HFR of in focus stars.
