This is a feature suggestion, not a bug.

The majority of the F200 (constant value in record) warnings which I have seen, have been for record 0. I think that a F200 warning for record 0 is almost certain to be spurious, and hence should be suppressed. The reason is that record 0 is often the initial value for a model run, and it is a common practice to initialize some of a model's variables with "unphysical" values such as a constant - the correct value will be computed after the first time step. That is, although the data is not physically correct, it is entirely as intended and cannot be considered to be an error.

For my own purposes I wrote (in Python) a filter to read the QC tool's output and eliminate all F200 warnings for record 0. I think this sort of thing also could be done in the QC tool itself.
