No idea, you're the expert here - probably that's easier to evaluate in comparison to your original, even shorter report.

Why not have two reports? If your final report has much less false positives and probably even generally with a higher error severity (variableScope normally doesn't indicate an error, can it?), then people can concentrate on these first.

Now I don't know how long it takes to generate them, but one can still toggle between them.
