The way you asked the question suggests you aren't reading the source
code with an eye to modifying it. That's fine, but I don't think other
approaches are likely to work.

This is all about a more complex mapping from transmitted bits (from the
6045M, which rtl_433 pretty much outputs verbatim) to desired semantics.
If there is processing from the strike count field to some de-wrapped or
delta strike count, as you suggest, that seems like an obvious place to
have code to deal with storm_distnance (set to logical NULL if this
record isn't reporting new strikes).
